Description of key information

Octanol Water partition co-efficient (Log Pow) value of 4-aminoazobenzene-3, 4’-disulphonic acid was estimated to be -0.91 at 25 deg C. 

Key value for chemical safety assessment

Log Kow (Log Pow):
-0.91
at the temperature of:
25 °C

Additional information

On the basis of prediction using EPI MPBVP v1.43, Danish (Q) SAR and SRC database (2016), Octanol Water partition co-efficient (Log Pow) value of 4-aminoazobenzene-3, 4’-disulphonic acid was estimated to be -0.91 at 25 deg C. This value indicates that 4-aminoazobenzene-3, 4’-disulphonic acid is hydrophilic in nature.
