NIST Chemistry WebBook

carefully curated property data on a large number of organic compounds, and a few common inorganics. Included data are thermochemical, thermodynamic, gas phase ion and spectral data.

This free chemical property database is developed by the U.S. National Institute of Standards and Technology (NIST). The WebBook is a compilation of property data that is reported in the primary literature.

Report a Problem


a free chemical structure database that mines the web for chemical property data. A secondary source of properties, ChemSpider provides well-referenced basic properties, experimental properties and predicted properties to over 67 million substances. 

Search by chemical name, chemical identifier and chemical structures to find:

  • Literature references
  • Physical properties
  • Interactive spectra
  • Chemical suppliers

Finding Patents

A patent is a protection granted by a government that gives the owner the right to keep others from making, using or selling an invention. A Canadian patent applies within Canada for 20 years from the date of filing of a patent application.

Identifying the CAS Registry Number of Compounds

CAS Registry Numbers (CAS RN) are unique numeric identifiers assigned to specific substances by the Chemical Abstract Service (CAS), a department of the American Chemical Society. CAS RNs are useful when substance searching in chemistry databases, because a single search by CAS RN retrieves results for chemical names, synonyms, trade names, and systematic names of the same substance.
If you know the chemical name you can find its CAS RN by searching the following databases.
