The Physical Properties Database (PHYSPROP) contains chemical structures, names and physical properties for over 25,250 chemicals. Physical properties are collected from a wide variety of sources, and include experimental, extrapolated, and estimated values for melting point, boiling point, water solubility, octanol-water partition coefficient, vapor pressure, pKa, Henry's law constant, and OH rate constant in the atmosphere.

Currently, PHYSPROP contains the following number of experimental records: Melting Point (10120), Boiling Point (6629), Water Solubility (6340), Octanol-Water Partition Coefficient (13250), Vapor Pressure(2837), pKa (1652), Henry's Law Constant (1713), OH Rate (500).

使用说明: PHYSPROP is available in ISISBase format (MDL Information Systems, Inc.). This program allows PHYSPROP to be searched by substructure, name fragment, or any of the physical properties.

备注: PHYSPROP is also available in other formats (SD File, MS-Excel97, MS-Access, etc.).
