Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
