Research Fundamentals: Property Data

Property data intro

Chemical and Physical Property Data


Physical and chemical properties are first reported in the primary chemical literature (i.e. journal articles and patent applications). Later, book editors and database providers compile the data into tables and charts so one can easily find multiple properties for a single compound. The UF Libraries have many print and online data compilations where you can find property information. Many of the resources on the recommendations page are also useful for finding property data. 

Property data sources

Quick Property Data Links

CRC Handbook of Chemistry and PhysicsA part of CHEMnetBASE, one of the most popular reference books for tabulated physical and chemical data. Includes full search capability. Requires UF Authentication
NIST Chemistry WebBookThermochemical data, IR spectra, UV/Vis spectra, electronic and vibrational spectra, constants of diatomic molecules(spectroscopic data), ion energetics data, thermophysical property data.
SciFinderSome property data is reported in the SciFinder database along with references to primary literature reporting those values. You can search by substance name or structure. Requires UF Authentication
Reaxys: Sort your substance search by a large variety of property data filters. Try using the "Query Builder" function on the top menu with the desired "physical data" filters.Requires UF Authentication
ChemIDplus Advanced: A free database of 380,000 chemical compounds. Records consist of name, synonyms, CAS number, molecular formula, and direct links to biomedical resources.
ChemSpider:  Freely accessible, validated database of over 26 million substances from over 400 data sources. Links to primary research where available and verified.
TOXNETDatabases on toxicology, hazardous chemicals, environmental health, and toxic releases.
Protein Data Bank (PDB): The PBD is a freely accessible database of 3D protein structures, containing data submitted by biochemists and biologists worldwide. Free software, including UnityMol and VMD, can be used to visualize protein structures. 
BRENDA: The Comprehensive Enzyme Information System (called BRENDA) is a free to access, comprehensive repository of enzyme data. It is particularly useful for gathering enzyme kinetic data. 

Sigma-Alrich Website: Although Sigma-Aldrich is a commercial chemical supply company,  their website offers a large amount of physical property and spectral data for commercially available products.
