Additional information

On the basis of prediction using EPI MPBVP v1.43, Danish (Q) SAR and SRC database (2016), Vapour pressure of 4-aminoazobenzene-3, 4’-disulphonic acid was estimated to be 0.00000000000000466 Pa at 25 deg C. It is reported as 0.000000001 Pa for the chemical safety assessment due to the limitation in the field.
