Other web sites that offer searchable chemical databases, recommended by Scorecard.
If you want more detailed information about a chemical than Scorecard provides, there are several on-line and library resources Scorecard recommends for further research.

CambridgeSoft Chemfinder
Chemfinder gives basic physico-chemical data and molecular structures for chemicals, and provides links to international data sources addressing specific chemicals.

Hazardous Substances Data Bank
HSDB focuses on the toxicology of potentially hazardous chemicals, and includes peer-reviewed information on human exposure, industrial hygiene, emergency handling procedures, environmental fate, and regulatory requirements.

Search the National Library of Medicine's cluster of databases on toxicology, hazardous chemicals, and related areas.

University of Akron Hazardous Chemicals Database
The Hazardous Chemicals Database provides physical data on chemicals and links to Department of Transportation safety guides that are valuable for emergency response.

Vermont Safety Information Resources - Material Safety Data Sheet Index
Material Safety Data Sheets (MSDSs) are published by chemical product manufacturers to inform workers and emergency personnel about toxic substances. MSDSs include information about toxicity, health effects, first aid, proper storage and disposal, protective equipment, and spill/leak procedures. MSDSs reflects the hazards of working with a substance in an occupational setting, and are not directed at consumers or the general public. Vermont SIRI searches typically retrieve MSDSs for the specified chemical.

Cornell University Material Safety Data Sheet Repository
Cornell Repository searches typically retrieve MSDSs for products containing the specified chemical.
Scorecard provides qualitative summaries of the health hazards posed by a chemical (e.g., it is a suspected neurotoxicant), but not direct access to supporting toxicological data. These scientific studies are abstracted in several toxicity databases, which are available in libraries, from commercial vendors, and sometimes on-line. The major toxicity databases include:

The Registry of Toxic Effects of Chemicals Substances (RTECS)
RTECS is a database of toxicological information compiled by the National Institute for Occupational Safety and Health. It contains summary information about the types of health effects chemicals can cause and the concentrations at which toxicity is known to occur. It is available from several commercial vendors at, and can often be found at major public or university libraries.

MEDLINE is the National Library of Medicine's premier bibliographic database covering the fields of medicine, nursing, dentistry, veterinary medicine, the health care system, and the preclinical sciences. MEDLINE contains bibliographic citations and author abstracts from more than 4,600 biomedical journals published in the United States and 70 other countries.
