Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No data evaluating the chronic toxicity of 2-hexyldecanoic acid[4-(6-tert-butyl-7-chloro-1H-pyrazolo[1,5-b][1,2,4]triazol-2-yl)phenylcarbamoyl]methylester

(UM-235) to fish are available. The environmental exposure assessment performed for this substance (see Chapters 9 and 10 of the CSR for detailed information) shows that the Risk Characterization Ratios (i.e. PEC/PNEC ratio) in the aquatic compartment (freshwater and marine) are < 1 and therefore, under the current exposure conditions, UM-235 does not pose a risk to aquatic organisms and further testing is not deemed necessary according to Regulation (EC) No. 1907/2006, Annex XI, section 3. Due to the absence of chronic experimental data and the lack of toxic effects in the acute aquatic toxicity tests, surrogate PNEC values have been derived using the water solubility value as worst-case for exposure calculations.
