Conclusions:
The partition coefficient(n-octanol/water) of test substance Benzyl phenylacetate (CAS No. 102-16-9)was determined as per the HPLC method (OECD Guideline-117). The Log Pow value was determined to be 3.4785 ± 0.0065 at 25°C.
Executive summary:

The partition Coefficient n-octanol/water of Benzyl phenylacetate(CAS No.102-16-9) was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 117 for testing of Chemicals.The reference substances were chosen according to functional group similarity with the test substance and calibration graph was prepared. The reference substances were benzene, biphenyl, methyl benzoate, benzyl benzoate, 4-acetylpyridine, toluene, ethylbenzene, n-butyl benzene and naphthalene, having Pow value ranging from 0.5 to 4.6. TheLog Pow value was determined to be 3.4785 ± 0.0065 at 25°C.
