Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key studies for environmental fate end-points have been conducted to recognised testing guidelines or using validated QSAR models.

Additional information


The substance is not readily biodegradable (0% within 28 days).

The estimated half-life time of the test substance at pH 4 and pH 7 is higher than one year under representative environmental conditions (25°C): the substance is hydrolytically stable.

The BCFs are in the range of 689 -758. The substance is not bioaccumulative according PBT criteria.

Transport and distribution

The substance exhibits a high potential for adsorption to soil (logKoc = 3.5).

From the water surface, the substance will not evaporate into the atmosphere (Henry's Law constant = 2.23 x 10 -7 Pa.m3/mole).

Thus, if released into the environment, the substance will mainly be distributed to soil and sediment.
