Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Phototransformation in air

Based on computations with computer programme SRC AOP v1.92 (EPISuite v4.11), the degradation rate constant with OH radicals (concentration: 1.56E+6 molecule/cubic cm) is 0.544 cubic cm/molecules*s. This equals a half-life in air of 19.6662 d.



The rate constant k and half-life were determined at 20 °C for pH 4 = 8.5E-5 h-1 and 8122 h, respectively, for pH 7 = 8.8E-4 and 784 h, respectively, and for pH 9 = 0.0217 h-1 and 32 h, respectively.
