Executive summary:

The partition Coefficient n-octanol/water of test chemical N,N,N-trimethylanilinium chloride (CAS No. 138-24-9) was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 117 for testing of Chemicals. A test item solution was prepared by accurately weighing 4 mg of test item and diluted with ACN up to 10 ml. Thus, the test solution concentration was 400 mg/l. The pH of test substance was 7.3. The reference substances were chosen according to functional similarity with the test substance and calibration graph was prepared. The reference substances were Phenol, Benzene, 2 -Nitrophenol, Nitrobenzene, Diphenylamine having Pow value ranging from 1.5 to 3.4. The Log Pow value of the test chemical N,N,N-trimethylanilinium chloride was determined to be 0.542 ± 0.020 dimensionless at 25°C. On the basis of this value, test chemical N,N,N-trimethylanilinium chloride can be considered to be hydrophilic in nature.
