Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The registration substance is a transported isolated intermediate and will therefore be used under strictly controlled conditions in line with article 18, 4.(b) of the REACH regulation EC1907/2006 which states "procedural and control technologies shall be used that minimise emission and any resulting exposure", and therefore no exposure to the environment is expected. A CSR is not needed for this substance and therefore PNEC values have not been calculated.
Conclusion on classification
Classification and labelling has been based upon the key information for the ecotoxicity endpoints. The results of these studies are as follows:
Short-term toxicity
96 h LC50 (for fish) = 45.2 µg/L
48 h EC50 (for daphnia) = 1.3 mg/L
72 h EC50 (for algae) = 17 µg/L
Long-term toxicity
21 day NOEC (for daphnia) = 14 µg/L (TWA) based on reproductive output, mortality of parentals, body length
It should also be considered that the substance does not meet the definition of a readily biodegradable substance with only 2 % degradation after 28 days.
The worst case short-term result is the 72 h EC50 to algae of 17 µg/L. This value was also used to classify for long-term toxicity as it results in a stricter classification in accordance with Table 4.1.0 (b)(iii) than the long-term daphnia result. Therefore the appropriate classification for this substance with regard to the environment is as follows:
Hazardous to the aquatic environment. Acute Category 1 and Chronic Category 1
M factor = 10 (applied for both acute and chronic toxicity)
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.
