Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Due to the rapid hydrolysis of the parent compound, the PNEC derivation will be based on the results for the hydrolysis product methanol
Conclusion on classification
Following
DSD/DPD, the substance is not to be classified as dangerous for the
environment since the acute toxicity of the hydrolysis product methanol
is > 100 mg/L. Moreover, the hydrolysis product is readily biodegradable
and the log Kow is < 3 (no experimentally determined BCF).
Following GHS, the substance is not to be classified as hazardous to the
aquatic environment since the acute toxicity of the hydrolysis product
is > 100 mg/L. Moreover, the hydrolysis product is readily biodegradable
and the log Kow is < 4 (no experimentally determined BCF)."
Data from HCl have not been taken into consideration as observed effects are caused by a pH-shift in the test medium.
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.
