Chemistry: Web Resources

compiles chemical information from many sources

From U.S. National Library of Medicine. Provides chemical structure, property, and toxicity searching.

Global Chemical Network

ChemSpider is a free chemical structure database providing fast access to over 25 million structures, properties and associated information. By integrating and linking compounds from more than 400 data sources, ChemSpider enables researchers to discover the most comprehensive view of freely available chemical data from a single online search. It is owned by the Royal Society of Chemistry.

contains CAS Registry Numbers for approximately 7,900 chemicals of widespread general public interest

Source for Materials Information

from National Institute of Standards and Technology. Chemical and physical property data for chemical species provided in the site are from collections maintained by the NIST Standard Reference Data Program and outside contributors. Data in the WebBook system are organized by chemical species. The WebBook system allows users to search for chemical species by various means.

NIST scientific and technical data cover a broad range of substances and properties from many different scientific disciplines.
