Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A measured Koc value of 12000 (log Koc 4.07) indicates that the substance has strong potential to adsorb to sediment/soil.

Henry coefficient: To assess the volatilisation potential of the substance a Henry's law constant was calculated using EUSES, which showed a value of 36.6 Pa. m3/mol (at 12 °C). Based on this value partitioning from water to air may be expected.

Based on Level III environmental distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 33885-52-8 and the measured physico-chemical parameters (water solubility and log Kow) as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (83.8%) and water (15.8%) with minor amounts to air (0.1%) and sediment (0.3%).

The SimpleTreat model simulates the distribution of the substance in a Sewage Treatment Plant. Model calculations (default assumptions, local) show that 0% of the substance will be degraded and that 30.5%, 53.2% and 16.3% will partition to water, sludge and air, respectively.
