Chemistry: Reference Sources

Searchable chemical identification database from the National Library of Medicine (a TOXNET resource). Provides chemical structure (in 3D if you choose), chemical properties, names & synonyms, RN, and various toxicity data.

A Guide to IUPAC Nomenclature of Organic Compounds

Gateway to the data collections of the National Institute of Standards and Technology

2483 compound database has been compiled by Harold M. Bell at Virginia Tech

PubChem, released in 2004, provides information on the biological activities of small molecules. PubChem is organized as three linked databases within the NCBI's Entrez information retrieval system. These are PubChem Substance, PubChem Compound, and PubChem BioAssay. PubChem also provides a fast chemical structure similarity search tool.

Search catalog for chemical products

an integrated spectral database system for organic compounds, which includes 6 different types of spectra under a directory database of the compounds. The spectra are EI mass, 1H decoupled 13C NMR, 1H NMR pattern (90 and/or 400 MHz), 1H NMR parameter (300 MHz pattern generated), FT-IR, laser-Raman, and ESR.
