Description of key information

In the atmosphere a half-life of 3.2 hours for 2-(morpholin-4-ylsulfanyl)-1,3-benzothiazole due to reaction with photochemically produced hydroxyl radicals is estimated by AOPWIN v1.92 with a rate constant of 1.20 *10-10cm3/(molecule*sec), considering an OH-concentration of 500,000 radicals/cm³ as a 24-h average (Currenta, 2010).  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.

Key value for chemical safety assessment
