Friedrich Wöhler FRS(For) HonFRSE was a German chemist known for his work in both organic and inorganic chemistry, being the first to isolate the chemical elements beryllium and yttrium in pure metallic form. He was the first to prepare several inorganic compounds, including silane and silicon nitride.
Friedrich August Kekulé, later Friedrich August Kekule von Stradonitz, was a German organic chemist. From the 1850s until his death, Kekulé was one of the most prominent chemists in Europe, especially in the field of theoretical chemistry. He was the principal founder of the theory of chemical structure and in particular the Kekulé structure of benzene.
A CAS Registry Number is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry. This registry includes all substances described since 1957, plus some substances from as far back as the early 1800s; it is a chemical database that includes organic and inorganic compounds, minerals, isotopes, alloys, mixtures, and nonstructurable materials. CAS RNs are generally serial numbers, so they do not contain any information about the structures themselves the way SMILES and InChI strings do.
Leopold Gmelin was a German chemist. Gmelin was a professor at the University of Heidelberg. He worked on the red prussiate and created Gmelin's test, and wrote his Handbook of Chemistry, which over successive editions became a standard reference work still in use.
Chemical Abstracts Service (CAS) is a division of the American Chemical Society. It is a source of chemical information and is located in Columbus, Ohio, United States.
Friedrich Konrad Beilstein, was a Russian chemist and founder of the famous Handbuch der organischen Chemie. The first edition of this work, published in 1881, covered 1,500 compounds in 2,200 pages. This handbook is now known as the Beilstein database.
Butan-2-ol, or sec-butanol, is an organic compound with formula CH3CH(OH)CH2CH3. Its structural isomers are 1-butanol, isobutanol, and tert-butanol. 2-Butanol is chiral and thus can be obtained as either of two stereoisomers designated as (R)-(−)-butan-2-ol and (S)-(+)-butan-2-ol. It is normally encountered as a 1:1 mixture of the two stereoisomers — a racemic mixture.
Biphenyl is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen may use the prefixes xenyl or diphenylyl.
Wilhelm Rudolph Fittig was a German chemist. He discovered the pinacol coupling reaction, mesitylene, diacetyl and biphenyl. Fittig studied the action of sodium on ketones and hydrocarbons. He discovered the Fittig reaction or Wurtz–Fittig reaction for the synthesis of alkylbenzenes, he proposed a diketone structure for benzoquinone and isolated phenanthrene from coal tar. He discovered and synthesized the first lactones and investigated structures of piperine, naphthalene, and fluorene.
Crotonic acid ((2E)-but-2-enoic acid) is a short-chain unsaturated carboxylic acid described by the formula CH3CH=CHCO2H. The name crotonic acid was given because it was erroneously thought to be a saponification product of croton oil. It crystallizes as colorless needles from hot water. With a cis-alkene, Isocrotonic acid is an isomer of crotonic acid. Crotonic acid is soluble in water and many organic solvents. Its odor is similar to that of butyric acid.
MDL Information Systems, Inc. was a provider of R&D informatics products for the life sciences and chemicals industries. The company was launched as a computer-aided drug design firm in January 1978 in Hayward, California. The company was acquired by Symyx Technologies, Inc. in 2007. Subsequently Accelrys merged with Symyx. The Accelrys name was retained for the combined company. In 2014 Accelrys was acquired by Dassault Systemes. The Accelrys business unit was renamed BIOVIA.
The CRC Handbook of Chemistry and Physics is a comprehensive one-volume reference resource for science research. First published in 1914, it is currently in its 104th edition, published in 2023. It is sometimes nicknamed the "Rubber Bible" or the "Rubber Book", as CRC originally stood for "Chemical Rubber Company".
The SPRESI data collection is one of the largest databases for organic chemistry worldwide. The database covers the scientific literature from 1974 to 2014, focusing on organic synthesis. It contains information on 5.8 million chemical structures and 4.6 million chemical reactions abstracted from 700,000 references.
Methyl acrylate is an organic compound, more accurately the methyl ester of acrylic acid. It is a colourless liquid with a characteristic acrid odor. It is mainly produced to make acrylate fiber, which is used to weave synthetic carpets. It is also a reagent in the synthesis of various pharmaceutical intermediates. Owing to the tendency of methyl acrylate to polymerize, samples typically contain an inhibitor such as hydroquinone.
The Gmelin database is a large database of organometallic and inorganic compounds updated quarterly. It is based on the German publication Gmelins Handbuch der anorganischen Chemie which was originally published by Leopold Gmelin in 1817; the last print edition, the 8th, appeared in the 1990s. Although published over many decades, the printed series was not uniform in coverage or currency. Some elements are represented only by decades-old and not updated slim summary volumes. Others have numerous supplements. Most later supplement volumes focused on an element's organic complexes. Each volume lists its literature coverage date.
Reaxys is a web-based tool for the retrieval of information about chemical compounds and data from published literature, including journals and patents. The information includes chemical compounds, chemical reactions, chemical properties, related bibliographic data, substance data with synthesis planning information, as well as experimental procedures from selected journals and patents. It is licensed by Elsevier.
The German Chemical Society is a learned society and professional association founded in 1949 to represent the interests of German chemists in local, national and international contexts. GDCh "brings together people working in chemistry and the molecular sciences and supports their striving for positive, sustainable scientific advance – for the good of humankind and the environment, and a future worth living for."
Theodor Weyl was a German chemist and hygienist born in Berlin.
Johann Gasteiger is a German Chemist and a Chemoinformatician on which he wrote and edited various books.
Olga García Mancheño is an organic chemistry professor at the University of Münster in Germany. García Mancheño directs an organic chemistry research group at University of Münster that focuses on development of new catalytic methods with the goal of developing sustainable synthetic routes to accomplish carbon-hydrogen functionalization, organic chemical rearrangements, and photocatalyzed chemical reactions.
