Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Read-across substance, OECD Guideline 209, key study, validity 2:
3h-EC50 = 39.6 mg/L
Key value for chemical safety assessment
- EC50 for microorganisms:
- 39.6 mg/L
Additional information
The toxicity of an analogue substance to activated sludge was investigated according to OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test). 3h EC50 of 39.6 mg/L was observed (Bayer AG, 1986). Based on chemical similarity (isomers with different position of the alkyl group), no significant difference is anticipated with the present dossier substance, so the read-across is considered justified for a key study.
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.
