Additional information
The water solubility determination of test item Sodium 3-(p-anilinophenylazo)benzenesulphonate (CAS No. 587-98-4) was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of (Sodium 3 - (p-anilinophenylazo)benzenesulphonate of 587-98-4 ) in water was found to be 23431 mg/L at 25°C. This indicates that the substance is very soluble in water.
Other supporting data from various reliable sources such as authoritative database and handbooks also indicates that the chemical sodium 3-[(4-anilinophenyl)diazenyl]benzenesulfonate to be moderately soluble to soluble in water.
