Description of key information

Photochemical reaction with OH radicals

- Concentration of OH radicals: 1.5E6 OH/cm3

- Degradation rate constant: 257.2325E-12 cm3/molecules*s (cis-isomer); 264.8325E-12 cm3/molecules*s (trans-isomer)

- Other: assuming a 12-hour day

DT50: 29.938 min (Cis-isomer)

DT50: 29.079 min (Trans-isomer)

Key value for chemical safety assessment

Half-life in air:
29.938 min

Additional information

Half-life and degradation rates have been estimated with AOPWIN v1.92. The result for the trans-isomer has been reported as representative for Chemical Safety Assessment, as the most abundant initial species.
