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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 264-637-8 | CAS number: 64051-50-9
Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
Description of key information
No bioaccumulation experimental studies are known to have been undertaken. Therefore Bioconcentration Factors (BCF) have been estimated using EPI Suite, based on a log Kow of 13.9396, and using the regression-based and Arnot-Gobas methods.
Key value for chemical safety assessment
- BCF (aquatic species):
- 5.29 L/kg ww
Additional information
No bioaccumulation experimental studies are known to have been undertaken. Therefore the following Bioconcentration Factors (BCF) have been estimated using EPI Suite, based on a log Kow of 13.9396, and using the regression-based and Arnot-Gobas methods:
Regression-based method:
o Log BCF: 0.72 (BCF = 5.29 L/kg wet-wt)
Arnot-Gobas BCF & BAF Methods (including biotransformation rate estimates):
o Log BCF (upper trophic) = -0.045 (BCF = 0.9017 L/kg wet-wt)
o Log BAF (upper trophic) = 1.645 (BAF = 44.2 L/kg wet-wt)
o Log BCF (mid trophic) = -0.025 (BCF = 0.9447 L/kg wet-wt)
o Log BAF (mid trophic) = 1.293 (BAF = 19.64 L/kg wet-wt)
o Log BCF (lower trophic) = -0.020 (BCF = 0.9552 L/kg wet-wt)
o Log BAF (lower trophic) = 1.029 (BAF = 10.7 L/kg wet-wt)
Arnot-Gobas BCF & BAF Methods (assuming a biotransformation rate of zero):
o Log BCF (upper trophic) = -0.044 (BCF = 0.9028 L/kg wet-wt)
o Log BAF (upper trophic) = 1.704 (BAF = 50.61 L/kg wet-wt)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
