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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Conclusion on classification
The test substance is not readily biodegradable according to OECD criteria and considered not bioaccumulative according PBT criteria due to the BCF of 689 - 758.
Three trophic levels in aquatic toxicology are covered by acute toxicity tests. In all three tests no acute toxic effects could be observed up to the limit of solubility. The test substance is with high probability not acutely harmful to aquatic organisms.
Additionally, a water solubility of 1.9 and 2.8 mg/L was measured (> 1 mg/L).
According to Regulation (EC) No. 1272/2008 a "safety net" classification Chronic Category 4 has to be used for poorly soluble substances (solubility < 1 mg/L) for which no acute toxicity is recorded at levels up to the water solubility, and which are not rapidly degradable and have an experimentally determined BCF ≥ 500 (or, if absent, a log Kow ≥ 4), indicating a potential to bioaccumulate; they will be classified in this category unless other scientific evidence exists showing classification to be unnecessary.
However, since the test substance is not poorly soluble and has a water solubility of above 1 mg/L the test substance is not classified.
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.
