Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 results of the study show that only 6% of 2-methylpropane-2-thiol was degraded in 63 days, which indicates that 2-methylpropane-2-thiol is not expected to be readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The results indicate that 2-methylpropane-2-thiol is not inhibitory to microorganisms, nor is it readily biodegradable. The results have been taken from Gancet (2010) - a GLP compliant, 63 day, aerobic test on secondary effluent, following OECD guideline 301D (Ready Biodegradability - Closed Bottle Test).
