Description of key information

WATERNT v 1.01 and WSKOW v 1.42 were used to estimate the water solubility of the test chemical.The estimated water solubility of 2,4-Diaminobenzenesulfonic acid was determined as 1000000mg/l at 25 deg C. This value suggests that 2,4-Diaminobenzenesulfonic acid is highly soluble in water.

Key value for chemical safety assessment

Water solubility:
1 000 000 mg/L
at the temperature of:
25 °C

Additional information

Data from various modelling and authoritative databases suggests that the water solubility of the test chemical lies in the range of 6000 - 1000000 mg/l.

The water solubility value used for the chemical safety assessment of 2,4 -Diaminobenzensulfonic acid was 1000000 mg/l at 25 deg C.

This value indicates that 2,4 -Diaminobenzenesulfonic acid is highly soluble in water.
