Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
short-term toxicity to fish
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification
Justification for type of information:
This substance is expected to hydrolyse rapidly to phenol in the environment. For the environmental assessment phenol PNECs have been used. However, in order to comply with the requirements of REACH, QSAR data on the substance is being provided since "rapid hydrolysis" is not a standard justification for waiving the endpoint.
