Toxicological Profiles (ATSDR) (
Author: ATSDR (Agency for Toxic Substances and Disease Registry)
Scroll down two pages to see Substance Index. Over 309 profiles in final or draft format. "By Congressional mandate, the Agency for Toxic Substances and Disease Registry (ATSDR) produces "toxicological profiles" for hazardous substances found at National Priorities List (NPL) sites. These hazardous substances are ranked based on frequency of occurrence at NPL sites, toxicity, and potential for human exposure. Toxicological profiles are developed from a priority list of 275 substances."

Merck Index: an encyclopedia of chemicals, drugs, and biologicals (

The Merck Index contains over 11,000 entries (referred to as monographs) mostly for single substances and related compounds (isomers, salts, etc.). Some families of natural products and biological substances are included as well. Data provided include: chemical, generic, and brand names; CAS (Chemical Abstracts Service) registry numbers; physical data and literature references; structures and stereochemistry; toxicity; and information on therapeutic and non-medicinal uses.

The Merck Index Online also includes sections on: organic name reactions, and additional tables. The Merck Index can be searched by structure with installation of a free ChemDraw plug-in available on the structure search page.
