Description of key information
2,6-dibromo-4-cyanophenyl heptanoate is photolytically degraded in aqueous solution with a half-life of 18 hours to > 1 year.
Key value for chemical safety assessment
- Half-life in water:
- 1 yr
Additional information
The endpoint “phototransformation in water” 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. There are a total of two studies on the phototransformation in water available.
In a study conducted according to GLP and BBA part IV 6-1 the direct photodegradation of 2,6-dibromo-4-cyanophenyl heptanoate was investigated in aqueous solution. Using a Suntest irradiation apparatus the half-life DT-50 was determined to be 18.0 hours.
An estimation of the photolytic degradation of 2,6-dibromo-4-cyanophenyl heptanoate at solar irradiation conditions of Central Europe, as described in ECETOC (1984), calculated half-lives of >1 year.
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.
