Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

[BASIS FOR CALCULATION OF BCF]
- Estimation software: BCFBAF ver.3.01
- Summary Results:
Log BCF (regression-based estimate): 0.50 (BCF=3.16 L/kg wet-wt)
Biotransformation Half-Life (days): 0.00946 (normalized to 10 g fish)
Log BAF (Arnot-Gobas upper trophic): -0.05 (BAF=0.893 L/kg wet-wt)
Log Kow (experimental): -3.69
Log Kow used by BCF estimates: -3.69
Equation Used to Make BCF estimate: Log BCF = 0.50 (Ionic; Log Kow dependent)
Estimated Log BCF = 0.500 (BCF = 3.162 L/kg wet-wt)

Applicant's summary and conclusion

Conclusions:
Using log Kow of -3.69, a BCF of 3.162 was calculated with BCFBAF, version 3.01. This chemical is not expected to bioaccumulate.
