Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

laboratory half-life (20 °C): 9.1 day (median, n=11)
field half-life: 8.2 days (median, n=13)

Key value for chemical safety assessment

Additional information

Half-life values have been determined in several laboratory and field studies. The experimental data have been re-modelled using ModelManager software using Simple First Order (SFO) and First Order Multi-Compartment (FOMC) kinetics.

The re-modelled half-lives, superceding those described in the original test reports, ranged between 2.3 and 38.4 days. Out of 11 soils the new median of the laboratory half-lives was 9.1 days. Out of 13 soils the new median of the field half-lives was 8.2 days. The kinetics data used for the evaluation were obtained by testing either the R-enantiomer or the racemate.
