You can download datasets derived from PhysProp (like the "PhysProp Analysis" files) via Figshare or the EPA's Downloadable Data Sets page.
The physprop() function allows you to retrieve data by CAS number directly into your workspace. physprop database download
For modern data science needs, the provides curated PhysProp data. You can download datasets derived from PhysProp (like
Water solubility, Log Kow (octanol-water partition coefficient), and Henry’s Law Constant. The , maintained by the Syracuse Research Corporation
The database includes critical physicochemical and environmental fate properties for each entry:
Chemical names, CAS Registry Numbers, and SMILES strings for structure-based searching. Key Benefits for Researchers Scientific Databases - Environmental Chemistry - SRC, Inc.
The , maintained by the Syracuse Research Corporation (SRC) and primarily distributed through the EPA, is a cornerstone resource for experimental and estimated physical properties of over 41,000 chemicals. For researchers needing bulk data for environmental modeling or chemical analysis, a direct download is essential. How to Download the PhysProp Database
