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.
