Description of key information

Additional information

Based on the low vapour pressure value (0.0045 Pa at 20 °C) of 2-(4-tert-butylphenyl)-6-cyano-5-[bis(ethoxycarbonylmethyl)carbamoyloxy]-1 H-pyrrolo[1 ,2-b][1 ,2,4]triazole-7-carboxylic acid-2,6-di-tert-butyl-4-methyl-cyclohexyl ester (UC-141), volatilization of the substance and subsequent accumulation and transport through the atmospheric compartment is expected to be low. UC-141 is highly insoluble in water (< 0.08 mg/L at 20 °C) and has a high adsorption potential (log Koc > 5.63). Therefore, if released into the environment it will be mainly distributed in the sediment and soil compartments.
