Chemical Data Reporting

Chemicals in Commerce, as Reported in the 2012 CDR Cycle

During the 2012 reporting cycle, Chemical Data Reporting (CDR) information was provided by manufacturers (including importers) for 7,690 individual chemicals.

The chemical names are listed by their preferred Chemical Abstract index names on the Substance Registry Service (SRS) and not by their synonyms.

Note: Substances can have many synonyms and while a substance may have a record in the SRS, all the synonyms for that substance may not be in SRS. You can search the SRS if you know the Chemical Abstract Service (CAS) number for the chemical. Alternatively, you could search the Internet using your synonym to discover other synonyms with which you could search SRS.
