The Registry of Toxic Effects of Chemical Substances (RTECS) is a compendium of toxicological data
RTECS is a compendium of toxicological data that was built and maintained by the National Institute of Occupational Safety and Health (NIOSH) from 1971 through January 2001.
Symyx now produces the RTECS files using existing data selection criteria and rules established by NIOSH. The RTECS file is distributed quarterly to licensees under the terms of the License and Distribution Agreement entered into on October 29, 2001 between Symyx Technologies, Inc. and the United States Public Health Service within the Department of Health and Human Services.

Updates
RTECS is updated quarterly by Symyx and delivered to customers via the Symyx Download Center as three files:
