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 ...
A calculated octanol-water partition coefficient (Clog P) that does not exceed 5; Note that all numbers are multiples of five, which is the origin of the rule's name. As with many other rules of thumb, such as Baldwin's rules for ring closure, there are many exceptions.
A model compound for the lipophilic cellular membrane is 1-octanol (a lipophilic medium-chain fatty alcohol), so the logarithm of the octanol-water partition coefficient, known as LogP, is used to predict the solubility of a potential oral drug. This coefficient can be experimentally measured or predicted computationally, in which case it is ...
The distribution of a compound between water and octanol is used to calculate the partition coefficient, P, of that molecule (often expressed as its logarithm to the base 10, log P). Water/octanol partitioning is a relatively good approximation of the partitioning between the cytosol and lipid membranes of living systems. [5]
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 ...
