Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

using the US EPAs prediction software BCFBAF v3.01, the logBCF for the anion can be predicted to be 2.565 (BCF = 367 L/kg wet-wt)

Key value for chemical safety assessment

BCF (aquatic species):
367 L/kg ww

Additional information

--------------------------------- BCFBAF v3.01 --------------------------------

Summary Results: Log BCF (regression-based estimate): 2.56 (BCF = 367 L/kg wet-wt)

Biotransformation Half-Life (days) : 11.5 (normalized to 10 g fish)

Log BAF (Arnot-Gobas upper trophic): 2.45 (BAF = 283 L/kg wet-wt)


BCF (Bioconcentration Factor):


Log Kow (estimated) : 10.18

Log Kow (experimental): not available from database

Log Kow used by BCF estimates: 10.18

Equation Used to Make BCF estimate:

Log BCF = -0.49 log Kow + 7.554 + Correction


No Applicable Correction Factors

Estimated Log BCF = 2.565 (BCF = 367 L/kg wet-wt)
