Description of key information

An apparent hydrolysis rate of 1µg/hr and a t1/2 of 12.5 hours were determined for CBS in pH 7.0 buffered deionized water with light excluded at 25 °C (Monsanto, 1984). In the same condition, a complete hydrolysis of CBS in 24.9 hours was also observed with the sole hydrolysis product as benzothiazole identified (Monsanto, 1984). However, the expected degradation product as a result of stoichiometric hydrolysis (i.e. Cyclohexylamine) was not found.

Key value for chemical safety assessment

Additional information

Under oxidative environment of 0.5 M phosphate buffer at pH 6.5, trace amount of MBTS (CAS: 120-78-5) and MBT (CAS: 149-30-4) were also detected (Hansson & Agrup, 1993).
