The LOGKOW Database eliminates tedious literature searching and reduces the time and cost of obtaining partition coefficient data. A partition or distribution coefficient is the equilibrium ratio of the concentration of a substance dissolved in an organic solvent to the concentration of the same substance dissolved in water. The octanol/water coefficient (logKow) is the standard system which relates to biological activity and the environmental impact of chemicals.

• over 30,000 critically evaluated octanol/water partition coefficients for over 23,000 organic compounds including many recommended values.
• over 1,984 current literature references in Chemical Abstracts style.
• Acid dissociation constants (pKa).
• Chemicals identified by CAS Registry Number, SMILES notation & molecular formula.
• Information about the pH, temperature, phases analyzed, nature of the aqueous phase, method and, method reference.

Professionals in the design of - pharmaceuticals and medicinal chemicals; environmental impact analysis; risk assessment; toxicology; the prediction and correlation of thebioconcentration, soil and sediment absorption of organic pollutants; the solubility and modeling of the environmental fate of organic chemicals - will find this user-friendly databank extremely valuable. LogKow values are used in:
