Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The adsorption coefficient (Koc) of the substance has been determined to be 1800 L/kg (log Koc: 3.3), using the HPLC screening method (OECD 121).

Henry's law constant: To assess the volatilisation potential of the substance a Henry's law constant was calculated which gave a result of 0.0427 Pa. m3/mol (at 12°C). From the distribution modeling results it can be concluded that volatilisation is of minor importance in the environmental behaviour of the substance.

Based on Level III environmental distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 54982-83-1 and the measured physico-chemical parameters as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (73.6%) and water (24.7%) with small amounts to air (1.26%) and sediment (<1%).

The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant based on vapour pressure, water solubility, log Kow and (non) ready biodegradability. The model predicts that 74.1% of the substance will be degraded and that the remaining substance will partition to sludge (14.9%) and water (11%).
