Description of key information

The dissociation constants of MBS are pKa(HL/H+L) =2.65±0.30 and pKa(H2L/H+HL) = -6.82±0.20 at 25 °C, which were calculated by using ACD/Labs, v. 7.00 (Currenta, 2010).

Key value for chemical safety assessment

Additional information

According to QSAR estimation, this substance presents mainly as non-ionic form under environmentally relevant pH 5 - 9, and hence this estimate can be used for chemical safety assessment.
