File Description [top]

TSCA Chemical Substances Inventory (derived from the Initial Inventory of the Toxic Substances Control Act Chemical Substance Inventory) is a non-bibliographic dictionary listing chemical substances manufactured, imported, or in commercial use in the U.S. The Inventory was developed in response to Section 8(d) of the Toxic Substances Control Act (TSCA), public law 94-469. TSCA Initial Inventory is not a list of toxic chemicals since toxicity is not a criterion for inclusion in the list. For each substance the following are provided: CAS Registry number, preferred name, synonyms, and molecular formula. Confidential substances, definitions of complex substances with no appropriate molecular formulas, and additional synonyms, however, are not included in the online file.

TSCA Chemical Substances Inventory is prepared by the U.S. Environmental Protection Agency.

Sources [top]

Substance entries in TSCA Chemical Substances Inventory were derived from the May 1985 version of the Inventory and previous versions compiled by the U.S. Environmental Protection Agency, and the supplements of 1988, 1990, 1991 and 1993. Electronic updates to the list have been added whenever they become available. Because a common name may be used to identify more than one substance, verify the presence of the substance in the Inventory using the CAS Registry Number. Every record is assigned a CAS^® Registry Number which in unique to the specific substance.
