The National Registry of Certified Chemists (NRCC) is an American certification agency for chemistry professionals founded in 1967. [1]
In 1999, the organization name changed from National Registry in Clinical Chemistry to National Registry of Certified Chemists to reflect the broader scope of chemists. [1]

Chemistry is the scientific study of the properties and behavior of matter. It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds.
A chemist is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the relevant field. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists.
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.
The American Chemical Society (ACS) is a scientific society based in the United States that supports scientific inquiry in the field of chemistry. Founded in 1876 at New York University, the ACS currently has more than 155,000 members at all degree levels and in all fields of chemistry, chemical engineering, and related fields. It is one of the world's largest scientific societies by membership. The ACS is a 501(c)(3) non-profit organization and holds a congressional charter under Title 36 of the United States Code. Its headquarters are located in Washington, D.C., and it has a large concentration of staff in Columbus, Ohio.
The Merck Index is an encyclopedia of chemicals, drugs and biologicals with over 10,000 monographs on single substances or groups of related compounds published online by the Royal Society of Chemistry.
The National Republican Congressional Committee (NRCC) is the Republican Hill committee which works to elect Republicans to the United States House of Representatives.
A flavorist, also known as flavor chemist, is someone who uses chemistry to engineer artificial and natural flavors. The tools and materials used by flavorists are almost the same as that used by perfumers with the exception that flavorists seek to mimic or modify both the olfactory and gustatory properties of various food products rather than creating just abstract smells. Additionally, the materials and chemicals that a flavorist utilizes for flavor creation must be safe for human consumption.
John Ross was a scientist in physical chemistry and the Camille and Henry Dreyfus Professor of Chemistry at Stanford University.
Marion Frederick Hawthorne was an inorganic chemist who made contributions to the chemistry of boron hydrides, especially their clusters.
George McClelland Whitesides is an American chemist and professor of chemistry at Harvard University. He is best known for his work in the areas of nuclear magnetic resonance spectroscopy, organometallic chemistry, molecular self-assembly, soft lithography, microfabrication, microfluidics, and nanotechnology. A prolific author and patent holder who has received many awards, he received the highest Hirsch index rating of all living chemists in 2011.
Frank Albert Cotton FRS was an American chemist. He was the W.T. Doherty-Welch Foundation Chair and Distinguished Professor of Chemistry at Texas A&M University. He authored over 1600 scientific articles. Cotton was recognized for his research on the chemistry of the transition metals.
ChemSpider is a freely accessible online database of chemicals owned by the Royal Society of Chemistry. It contains information on more than 100 million molecules from over 270 data sources, each of them receiving a unique identifier called ChemSpider Identifier.
Fred Warren McLafferty was an American chemist known for his work in mass spectrometry. He is best known for the McLafferty rearrangement reaction that was observed with mass spectrometry. With Roland Gohlke, he pioneered the technique of gas chromatography–mass spectrometry. He is also known for electron-capture dissociation, a method of fragmenting gas-phase ions.
Benzene is an organic chemical compound with the molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar hexagonal ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.
A Chemist In Training (CIT) is a Canadian designation for someone who has obtained a degree from an accredited institution, that qualifies for registration with one of the provincial or territorial chemical professional associations, but has not yet achieved the additional requirements to become accredited as a Professional Chemist (P.Chem.).
Ralph Franz Hirschmann was a German American chemist who led a team that was responsible for the first organic synthesis of an enzyme, a ribonuclease.
Lloyd Albert Quarterman was an American chemist working mainly with fluorine. During the Second World War he was one of the first six African American scientists and technicians on the Manhattan Project.
Edward Marion Augustus Chandler was the second African American to receive a Ph.D. in chemistry while studying at University of Illinois at Urbana–Champaign and was a founding faculty member at Roosevelt University in Chicago.
The 2022 United States House of Representatives elections were held November 8, 2022, to elect representatives from all 435 congressional districts across each of the 50 U.S. states. Five of the six non-voting delegates from the District of Columbia and the inhabited U.S. territories were also elected. Numerous federal, state, and local elections, including the 2022 U.S. Senate elections, were also held on this date.
