Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The rate constant for the reaction of propane-2-thiol with OH radicals is 40.7 +/- 3.7 to 42.2 +/- 7.1 E-12 cm3 molecule-1 s-1. Using an equation of half-life = Ln2 / (OH concentration * rate constant * 60 * 60 * daylight length), and an OH concentration of 1.56 E6 and a daylight length of 12 hours, this gives an atmospheric half-life of 0.24 to 0.25 days.
Key value for chemical safety assessment
- Half-life in air:
- 0.25 d
Additional information
The results have been compiled from three studies. Atkinson (1989) is a review paper, which includes and extends previous review articles by the author (inlcuding Atkinson, 1987) and provides some general information about the experimental methods and conditions. Both Barnes papers (1986 and 1987) are non-GLP, non-guideline studies, with sound scientific principles, analytical monitoring and a control groups.
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.
