Find physical and chemical properties

CRC Handbook of Chemistry and Physics This link opens in a new window
Includes Physical Constants of Organic Compounds, data on chemical carcinogens, Critical constants, and more.
84th edition which includes the revised Physical Constants of Organic Compounds table, new data on chemical carcinogens, an expanded Critical constants table, and more.
SciFinder This link opens in a new window
Search the world's most comprehensive source of references, substances, and reactions in chemistry and related sciences.
Note: Restricted to UC Berkeley students, faculty, and staff. Requires creation of a personal account from an @berkeley.edu email address.
Indexes over 9,000 journals, patents, conferences, books, technical reports and dissertations related to chemistry, chemical engineering, materials science and the biomedical sciences. Relates to the print equivalent Chemical Abstracts.
Note: SciFinder-n is the next generation SciFinder platform. You can choose to use either until the old version is phased out, but SciFinder-n includes an updated search algorithm and enhanced features, including synthesis planning

Reaxys This link opens in a new window
Find property, reaction, synthesis, and bibliographic information for chemicals.
A web-based interface for three chemical information databases, Beilstein, Gmelin and the Patent Chemistry Database (PCD). Structure, reaction and citation searching are possible. Reaxys is a key resource for locating information on how to synthesis organic, inorganic and organometallic compounds. It is also a good source for critically evaluated data on on physical, chemical, spectral, bioactivity, or toxicological properties of chemical compounds.
SpringerMaterials: The Landolt-Bornstein Database This link opens in a new window
A comprehensive database that covers the physical and chemical properties in materials science.
Collection of fully evaluated data from all fields of physics, physical chemistry, geophysics, astronomy, biophysics and materials science & engineering.
Knovel Critical Tables This link opens in a new window
Contains interactive tables of the physical, solvent, and thermodynamic properties of inorganic and organic compounds and pure substances
Combined Chemical Dictionary This link opens in a new window
Find descriptive and numerical data and literature references on the chemical, physical and biological properties of compounds
Describes over 456,000 chemical substances.
PubChem This link opens in a new window
Information on chemical properties, structures, and bioactivity.
Includes three interlinked databases: PubChem Compound (standardized and validated chemical structures and properties), PubChem Substance (depositor-uploaded chemical information), and PubChem BioAssay (descriptions of bioactivity screens for chemicals in PubChem Substance).
