Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
2,6-dibromo-4-cyanophenyl heptanoate is photolytically degraded in air with a half-life of 47 h (~ 4 days assuming 12 hours irradiation per day).
Key value for chemical safety assessment
- Half-life in air:
- 47 h
Additional information
The endpoint “phototransformation in air” is not a data requirement for the registered substance. However, for the sake of completeness this endpoint is covered by a short summary of the available data.
In the available GLP study the chemical lifetime of 2,6-dibromo-4-cyanophenyl heptanoate in the atmosphere under tropospheric conditions was estimated according to the method described in the OECD Environment Monographs No. 61 (1992). The value of the reaction rate constant at 25 °C is 40.76E-7/s which corresponds to a half-life of about 47 daylight hours (~ 4 days assuming 12 hours irradiation per day).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
