Description of key information

In absence of light and oxygen 2-mercaptobenzothiazole is hydrolytically stable with no hydrolysis products observed and 85% recovery within 7 days (Monsanto, 1985). According to expert judgment MBT can be oxidized by atmospheric oxygen to 2,2`-dithiobisbenzothiazole (MBTS) in aqueous solution. Hansson & Agrup (1993) reported 60% conversion of MBT into MBTS in phosphate buffer at pH 6.5 within 2 hours with the presence of atmospheric oxygen.
