Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
Water solubility: 24400 mg/L at 32 Deg C
Executive summary:

The principle of the method being ‘weight of the chemical substance (solute)to dissolve in water to form a homogeneous solution of the solute in the solvent’, was referred to determine the water solubility of the substance.The water solubility of 4-sulphoanthranilic acid is found to be 24400 mg/L at 32°C using shake flask method. So, 4-sulphoanthranilic acid is considered to be highly soluble in water.
