Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

2-hexyldecanoic acid[4-(6-tert-butyl-7-chloro-1H-pyrazolo[1,5-b][1,2,4]triazol-2-yl)phenylcarbamoyl]methylester (UM-235) is not volatile due to its vapour pressure of 0.006 Pa. Hydrolysis is not expected to be a relevant pathway for degradation as the substance is highly insoluble in water (< 0.004 mg/L in aqua bidest). UM-235 is not readily biodegradable. The log Koc value of > 5.63 indicates a considerable potential for adsorption and hence distribution to the soil and sediment compartment if released into the environment. Based on the log Kow of 8.45, UM-235 exhibits a substantial potential for bioaccumulation in biota. The substance shows a tendency for adsorption to solid particles in view of the calculated log Koc values (> 5.63) and therefore, potential to be mainly distributed in the soil and sediment compartments if released into the environment.
