Description of key information

The partition Coefficient n-octanol/water of Benzene-1,4-diammonium sulphate(CAS No.16245-77-5) 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, 2,6- Diphenylpyridine, Triphenylamine, 4-Acetylpyridine, Diphenylamine, toluene, ethylbenzene, N-butylbenzene and naphthalene having Pow value ranging from 0.5 to 5.7. The Log Pow value was determined to be 0.8556 ± 0.0456 at 25°C.

KOWWIN v 1.68 was used to estimate the octanol - water partition coefficient of Benzene-1,4-diammonium sulphate. The octanol water partition coefficient of Benzene-1,4-diammonium sulphate was estimated to be 0.5590.

Based on these values, it can be considered that Benzene-1,4-diammonium sulphate is hydrophillic in nature.
