The following resources provide information regarding the chemical and physical properties of commonly used compounds and reagents. Depending on the resource, compounds can be searched for by name, CAS number, structure, physical properties, or other identifiers.
Provides thermochemical, thermophysical, and ion energetics data compiled by NIST under the Standard Reference Data program.
A free chemical structure database providing fast access to over 32 million structures, properties, and associated information.
Structure and nomenclature authority files used for the identification of chemical substances cited in National Library of Medicine (NLM) databases; provides links to many biomedical resources at National Library of Medicine (NLM) and on the Internet for chemicals of interest ranging from helpful drugs to potentially hazardous chemicals. Learn more about this database.
Since many chemicals used in lab are purchased through Sigma Aldrich, their catalog is an excellent resource for obtaining information on chemical and physical properties along with important safety information and complete material safety data sheets (MSDS).
ChemIDPlus Provides information on physical properties, toxicity, and regulatory information. Its upports compound searches by name, formula, structure, registry number, physical properties, and toxicity.
