Description of key information

Photochemical reaction with OH radicals
OVERALL OH Rate Constant = 166.2864 E-12 cm3/molecule-sec [Cis-isomer]
OVERALL OH Rate Constant = 173.8864 E-12 cm3/molecule-sec [Trans-isomer]
Computer programme: SRC AOP v1.92
Other: assuming a 12-hour day .
DT50: 0.772 h (Cis-isomer)
DT50: 0.738 h (Trans-isomer)

Key value for chemical safety assessment

Half-life in air:
0.738 h

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.
