Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
For MBS a hydrolysis half-life of ca. 24 h in buffered deionized water at pH 7.0 and 25°C with light excluded was observed. The hydrolysis products were identified to be mercaptobenzothiazole (CAS: 149-30-4), bezothiazole (CAS: 95-16-9) and morpholine (CAS: 110-91-8). The indirect atmospheric oxidation rate by reaction with OH-radicals was estimated by using AOPWIN v1.92 to be 1.20 *10-10cm3/(molecule*sec) and half-life thus 3.21 h. The estimated half-life in air of MBS is much shorter than 48 hours; and hence no potential for long-range transport of MBS in air is expected. Due to direct photolysis in water , the half-life of MBS in water was reported to be 0.78 hour.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
