Results and discussion
Any other information on results incl. tables
In aqueous solutions, 1,3-benzothiazole-2-thiol can be oxidised in presence of oxygen to 2,2`-dithiobisbenzothiazole. Analysed test solutions containing 84 mg/l 1,3-benzothiazole-2-thiol in 0.5 M phosphate buffer and 10% tetrahydrofuran at pH 6.5. After 2 hours reaction time 60% of 1,3-benzothiazole-2-thiol was converted to 2,2`-dithiobisbenzothiazole. The results reveal that the equilibrium between 1,3-benzothiazole-2-thiol and 2,2`-dithiobisbenzothiazole is highly influenced by the redox status of the medium.
Applicant's summary and conclusion
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.
