ChemSpider is a database of chemicals. ChemSpider is owned by the Royal Society of Chemistry.
A chemical database is a database specifically designed to store chemical information. This information is about chemical and crystal structures, spectra, reactions and syntheses, and thermophysical data.
The Royal Society of Chemistry (RSC) is a learned society in the United Kingdom with the goal of "advancing the chemical sciences". It was formed in 1980 from the amalgamation of the Chemical Society, the Royal Institute of Chemistry, the Faraday Society, and the Society for Analytical Chemistry with a new Royal Charter and the dual role of learned society and professional body. At its inception, the Society had a combined membership of 34,000 in the UK and a further 8,000 abroad. The headquarters of the Society are at Burlington House, Piccadilly, London. It also has offices in Thomas Graham House in Cambridge where RSC Publishing is based. The Society has offices in the United States at the University City Science Center, Philadelphia, in both Beijing and Shanghai, China and Bangalore, India. The organisation carries out research, publishes journals, books and databases, as well as hosting conferences, seminars and workshops. It is the professional body for chemistry in the UK, with the ability to award the status of Chartered Chemist (CChem) and, through the Science Council the awards of Chartered Scientist (CSci), Registered Scientist (RSci) and Registered Science Technician (RScTech) to suitably qualified candidates. The designation FRSC is given to a group of elected Fellows of the society who have made major contributions to chemistry and other interface disciplines such as biological chemistry. The names of Fellows are published each year in The Times (London). Honorary Fellowship of the Society ("HonFRSC") is awarded for distinguished service in the field of chemistry.
The database contains information on more than 63 million molecules from over 280 data sources including:
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.In the kinetic theory of gases, the term molecule is often used for any gaseous particle regardless of its composition. According to this definition, noble gas atoms are considered molecules as they are monatomic molecules.
The Human Metabolome Database (HMDB) is a comprehensive, high-quality, freely accessible, online database of small molecule metabolites found in the human body. Created by the Human Metabolome Project funded by Genome Canada. One of the first dedicated metabolomics databases, the HMDB facilitates human metabolomics research, including the identification and characterization of human metabolites using NMR spectroscopy, GC-MS spectrometry and LC/MS spectrometry. To aid in this discovery process, the HMDB contains three kinds of data: 1) chemical data, 2) clinical data, and 3) molecular biology/biochemistry data. The chemical data includes 41,514 metabolite structures with detailed descriptions along with nearly 10,000 NMR, GC-MS and LC/MS spectra.
Journal of Heterocyclic Chemistry is a peer-reviewed scientific journal summarizing progress in the field of heterocycle chemistry. It is a source for the ChemSpider database.
KEGG is a collection of databases dealing with genomes, biological pathways, diseases, drugs, and chemical substances. KEGG is utilized for bioinformatics research and education, including data analysis in genomics, metagenomics, metabolomics and other omics studies, modeling and simulation in systems biology, and translational research in drug development.
Each chemical is given a unique identifier, which forms part of a corresponding URL. For example, acetone is 175, and thus has the URL http://www.chemspider.com/Chemical-Structure.175.html
With reference to a given set of objects, a unique identifier (UID) is any identifier which is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. The concept have been formalized early in Computer science and Information systems, in general associating it to an atomic data type.
Acetone, or propanone, is the organic compound with the formula (CH3)2CO. It is a colorless, volatile, flammable liquid and is the simplest and smallest ketone.
The ChemSpider database can be updated with user contributions including chemical structure deposition, spectra deposition and user curation. This is a crowdsourcing approach to develop an online chemistry database. Crowdsourced based curation of the data has produced a dictionary of chemical names associated with chemical structures that has been used in text-mining applications of the biomedical and chemical literature.
A chemical structure determination includes a chemist's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of atoms in a molecule and the chemical bonds that hold the atoms together, and can be represented using structural formulae and by molecular models; complete electronic structure descriptions include specifying the occupation of a molecule's molecular orbitals. Structure determination can be applied to a range of targets from very simple molecules, to very complex ones.
Crowdsourcing is a sourcing model in which individuals or organizations obtain goods and services, including ideas and finances, from a large, relatively open and often rapidly-evolving group of internet users; it divides work between participants to achieve a cumulative result. The word crowdsourcing itself is a portmanteau of crowd and outsourcing, and was coined in 2006. As a mode of sourcing, crowdsourcing existed prior to the digital age.
A dictionary, sometimes known as a wordbook, is a collection of words in one or more specific languages, often arranged alphabetically, which may include information on definitions, usage, etymologies, pronunciations, translation, etc. or a book of words in one language with their equivalents in another, sometimes known as a lexicon. It is a lexicographical reference that shows inter-relationships among the data.
However, database rights are not waived and a data dump is not available; in fact, the FAQ even states that only limited downloads are allowed:therefore the right to fork is not guaranteed and the project can't be considered free/open.
Free content, libre content, or free information, is any kind of functional work, work of art, or other creative content that meets the definition of a free cultural work.
Open data is the idea that some data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control. The goals of the open-source data movement are similar to those of other "open(-source)" movements such as open-source software, hardware, open content, open education, open educational resources, open government, open knowledge, open access, open science, and the open web. Paradoxically, the growth of the open data movement is paralleled by a rise in intellectual property rights. The philosophy behind open data has been long established, but the term "open data" itself is recent, gaining popularity with the rise of the Internet and World Wide Web and, especially, with the launch of open-data government initiatives such as Data.gov, Data.gov.uk and Data.gov.in.
A number of available search modules are provided:
The ChemSpider database has been used in combination with text mining as the basis of chemistry document markup. ChemMantis,the Chemistry Markup And Nomenclature Transformation Integrated System uses algorithms to identify and extract chemical names from documents and web pages and converts the chemical names to chemical structures using name-to-structure conversion algorithms and dictionary look-ups in the ChemSpider database. The result is an integrated system between chemistry documents and information look-up via ChemSpider into over 150 data sources.
ChemSpider was acquired by the Royal Society of Chemistry (RSC) in May, 2009.Prior to the acquisition by RSC, ChemSpider was controlled by a private corporation, ChemZoo Inc. The system was first launched in March 2007 in a beta release form and transitioned to release in March 2008. ChemSpider has expanded the generic support of a chemistry database to include support of the Wikipedia chemical structure collection via their WiChempedia implementation.
A number of services are made available online. These include the conversion of chemical names to chemical structures, the generation of SMILES and InChI strings as well as the prediction of many physicochemical parameters and integration to a web service allowing NMR prediction.
SyntheticPages is a free interactive database of synthetic chemistry procedures operated by the Royal Society of Chemistry.Users submit synthetic procedures which they have conducted themselves for publication on the site. These procedures may be original works, but they are more often based on literature reactions. Citations to the original published procedure are made where appropriate. They are checked by a scientific editor before posting. The pages do not undergo formal peer-review like a scientific journal article but comments can be made by logged-in users. The comments are also moderated by scientific editors. The intention is to collect practical experience of how to conduct useful chemical synthesis in the lab. While experimental methods published in an ordinary academic journal are listed formally and concisely, the procedures in ChemSpider SyntheticPages are given with more practical detail. Informality is encouraged. Comments by submitters are included as well. Other publications with comparable amounts of detail include Organic Syntheses and Inorganic Syntheses . The SyntheticPages site was originally set up by Professors Kevin Booker-Milburn (University of Bristol), Stephen Caddick (University College London), Peter Scott (University of Warwick) and Dr Max Hammond. In February 2010 a merger was announced with the Royal Society of Chemistry's chemical structure search engine ChemSpider and the formation of ChemSpider|SyntheticPages (CS|SP).
ChemSpider is serving as the chemical compound repository as part of the Open PHACTS project, an Innovative Medicines Initiative. Open PHACTS will deploy an open standards, open access, semantic web approach to address bottlenecks in small molecule drug discovery - disparate information sources, lack of standards and information overload.

Dalton Transactions is a peer-reviewed scientific journal publishing original (primary) research and review articles on all aspects of the chemistry of inorganic, bioinorganic, and organometallic compounds. It is published weekly by the Royal Society of Chemistry. The journal was named after the English chemist, John Dalton, best known for his work on modern atomic theory. Authors can elect to have accepted articles published as open access. The editor is Andrew Shore. Dalton Transactions was named a "rising star" by In-cites from Thomson Scientific in 2006.
Chemical Entities of Biological Interest, also known as ChEBI, is a database and ontology of molecular entities focused on 'small' chemical compounds, that is part of the Open Biomedical Ontologies effort. The term "molecular entity" refers to any "constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer, etc., identifiable as a separately distinguishable entity". The molecular entities in question are either products of nature or synthetic products which have potential bioactivity. Molecules directly encoded by the genome, such as nucleic acids, proteins and peptides derived from proteins by proteolytic cleavage, are not as a rule included in ChEBI.
