Description of key information

The water solubility determination of test item 1,2-benzisothiazol-3(2H)-one 1,1-dioxide, sodium salt (CAS No. 128-44-9) was done gravimetrically as per the shake flask method using membrane filtration followed by air drying. The water solubility was determine to be 1495.5 g/L at 24 °C. Thus the 1,2-benzisothiazol-3(2H)-one 1,1-dioxide, sodium salt is considered to be soluble in water.

Key value for chemical safety assessment

Water solubility:
