Water solubility of 4-aminoazobenzene-3, 4’-disulphonic acid is estimated to be 1000000 mg/L at 25 deg C which indicates that the substance is very soluble in nature.
On the basis of prediction using EPI MPBVP v1.43 (2011), Water solubility of 4-aminoazobenzene-3, 4’-disulphonic acid is estimated to be 1000000 mg/L at 25 deg C which indicates that the substance is very soluble in nature.
In a report given by Center for Chemical Hazard Assessment Syracuse Research Corporation (1981), 4 aminoazobenzene- 3, 4-disulfonic-acid was determined to be soluble in hot water.
In a Syracuse Research Corporation data base (2016), Benzenesulfonic acid, 2 amino 5((4 sulfophenyl) was determined to be 124 mg/L at 25 deg C which indicate that the substance is slightly soluble in water.
Therefore, on the basis of above available data, 4-aminoazobenzene-3, 4’-disulphonic acid was very soluble to in hot water.
