Description of key information

Based on the prediction using AOPWIN v1.93 (EpiSuite v4.11), the OH radicals photodegradation of the substance is 93.0128E-12 cm³ molecule-1 s-1 and the related DT50 1.380 hours; or 4.14 hours (EUSES v2.1.1); this last value is more conservative and thus will be used for the environmental CSA.

Key value for chemical safety assessment

Half-life in air:
4.14 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 s-1
