Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Short-term toxicity to aquatic invertebrates:
Based on the prediction done by EPI suite, ECOSAR version 1.1, on the basis of similarity of structure to chemicals for which the aquatic toxicity has been previously measured by structure-activity relationships (SARs) program, the LC50 value for short term toxicity to aquatic invertebrates was predicted.
On the basis of this program, the LC50 value for short term toxicity to aquatic invertebrates was predicted to be 769.89mg/l for test chemical in 48 hrs.
Based on this value it can be concluded that the substance was considered to be not toxic to aquatic environment and cannot be classified as per the criteria mentioned in CLP regulation.
Another test was conducted to determine the short-term toxicity of test chemical on daphnia magna. Thus, the EC50 value of test chemical after 60min was concluded to be 10mg/L.
Toxicity to aquatic algae and cyanobacteria:
Based on the prediction done using the EPI Suite ECOSAR version 1.11, the short term toxicity on green algae was predicted for test chemical. On the basis of effects observed, the EC50 value for the test chemical was estimated to be 374.46mg/l for the duration of 96h. Based on this value, it can be concluded that the test chemical was non-toxic to green algae at environmentally relevant concentrations and can be considered as not-classified as per the CLP classification criteria.
