Description of key information
Study conducted to generally recognised scientific standards
Key value for chemical safety assessment
- Half-life in air:
- 129 h
Additional information
In a SRC AOP v1.92 calculation a degradation rate constant for the indirect photolysis of 2.98E-12 cm3/molecules*s was calculated. Therefore, the test substance has a half-life in air of 129 hours.
