The n-octanol-water partition coefficient, K ow is a partition coefficient for the two-phase system consisting of n-octanol and water. [1] K ow is also frequently referred to by the symbol P, especially in the English literature. It is also called n-octanol-water partition ratio. [2] [3] [4]

The partition coefficient between n-Octanol and water is known as the n-octanol-water partition coefficient, or K ow. [62] It is also frequently referred to by the symbol P, especially in the English literature. It is also known as n-octanol-water partition ratio. [63] [64] [65]
Bioconcentration factors can also be related to the octanol-water partition coefficient, K ow. The octanol-water partition coefficient (K ow) is correlated with the potential for a chemical to bioaccumulate in organisms; the BCF can be predicted from log K ow, via computer programs based on structure activity relationship (SAR) [7] or through ...
For nonionic organic contaminants, the K OC can be determined based on the octanol-water partition coefficient (K OW). C OC is the organic carbon normalized sediment concentration (micrograms per kilogram OC) and C d is the dissolved interstitial water concentration (milligrams per liter). The equation above can be rearranged to: C OC = K OC C d.
The properties of switchable solvents [53] [54] are caused by the strength of their conjugate acid's pKa and octanol-water partition coefficient ratio K ow. They must have a pKa above 9.5 to be protonated by carbonated water and also a log(K ow) between 1.2 and 2.5 to be switchable, otherwise they will be hydrophilic or hydrophobic. These ...
Partition coefficients are very important in pharmacology because they determine the extent to which a substance can pass from the blood (an aqueous solution) through a cell wall which is like an organic solvent. They are usually measured using water and octanol as the two solvents, yielding the so-called octanol-water partition coefficient.
The descriptor most often used in QSAR to determine the hydrophobicity of a compound is the octanol-water partition coefficient, log P. [16] MLC provides an attractive and practical alternative to QSAR. When micelles are added to a mobile phase, many similarities exist between the micellar mobile phase/stationary phase and the biological ...
