Chemical Technology

Common Chemistry is helpful to non-chemists who know either a name or CAS Registry Number® of a common chemical and want to pair both pieces of information. The CAS Registry Number is the universally recognized unique identifier of chemical substances and is often found on packaging and on articles of commerce.

Originally this online resource was created by Robert Husted at Los Alamos National Laboratory during his time as a Graduate Research Assistant, circa 1992. It was given a face lift during 2002/2003 by Mollie Boorman, then a student working at the Laboratory.

In 2011, it was again re-designed and updated by Maida Trujillo of the Chemistry Division web team with technical and writing assistance from Dave Hobart and Josh Smith, both of Chemistry Division.

This page is being offered as a public service. We have attempted to make it as complete as possible, but it remains an imperfect resource with ambiguities and errors.

The National Institute of Standards and Technology's, founded in 1901 and now part of the U.S. Department of Commerce, is one of the nation's oldest physical science laboratories. Today, NIST measurements are available via their website.

Links from PubChem's chemical structure records to other Entrez databases provide information on biological properties. These include links to PubMed scientific literature and NCBI's protein 3D structure resource.

A PubChem publication site provides links to published articles.

ASTM’s leadership in international standards development is driven by the contributions of its members: more than 30,000 of the world’s top technical experts and business professionals representing 150 countries. Working in an open and transparent process and using ASTM’s advanced electronic infrastructure, ASTM members deliver the test methods, specifications, guides, and practices that support industries and governments worldwide.

Non-profit organization dedicated to advancing science around the world by serving as an educator, leader, spokesperson & professional association.

David Wilner is a native of Georgia, USA, born just before the end of WWII. Mr. Wilner is happiest when he is explaining things in science (pontificating), so it is natural that he has been a science teacher in high school and a teacher of chemistry at Georgia Perimeter College.

CHF hosts conferences & lectures, supports research, offers fellowships & produces educational materials. The museum & public programs explore subjects ranging from alchemy to nanotechnology.

Collects together terminology definitions from IUPAC recommendations, from ISO and from the International Vocabulary of Basic and General Terms in Metrology.

IUPAC was formed in 1919 by chemists from industry & academia, who recognized the need for international standardization of weights, measures, names & symbols in chemistry as essential to the well being & continued success of scientific enterprise & to the smooth development & growth of international trade & commerce.
