Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

After evaporation or exposure to the air, the product will be rapidly degraded by photochemical processes

Key value for chemical safety assessment

Additional information

An AOP v1.92 calculation is available for the estimation of the photodegradation in the atmosphere. For this calculation a 24 -hour day as well as a sensitizer-concentration (OH-radicals) of 500 000 molecules/cm³ were assumed. The calculated rate constant of 0.0000000000947527 cm³/molecule-sec results in a half-life in the atmosphere of 0.169 days (4.064 hours).
