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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
Available information:
approx. LC50 (OECD 203, 96 h, Oncorhynchus mykiss, screening level study): 16.6 mg/L
Only a screening level study is available for short-term toxicity to fish. The result given above provides useful information about the corresponding properties of the substance. However the reliability, relevance and adequacy of the data are considered as limited and an overall reliability rating of 3 (= not reliable, according to the scoring system of Klimisch et al.) has been assigned. As a consequence, these data are not adequate for risk assessment purposes. However, the approx. LC50 result (or at least its order of magnitude) is considered as relevant and adequate for classification and labelling purposes. More details are given in the endpoint study record (Applicant's summary and conclusion - Conclusions).
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.
