0.75
Temp.:
25 °C
Remarks on result:
other: other details not available
Conclusions:
The octanol water partition coefficent log Pow of test chemical p-hydroxyphenylacetic acid (CAS no. 156-38-7) was determined to be 0.75 dimensionless. On the basis of this partition coefficient value it can be concluded that test chemical p-hydroxyphenylacetic acid (CAS no. 156-38-7) is hydrophilic in nature which is also supported by water solubility of test chemical.
