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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 662-772-0 | CAS number: 25601-41-6
Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Meets generally accepted scientific standards, well document and acceptable for assessment
- Justification for type of information:
- QSAR prediction: migrated from IUCLID 5.6
- Qualifier:
- according to guideline
- Guideline:
- other: no data
- Deviations:
- not applicable
- Principles of method if other than guideline:
- BCFBAF V3.00 accessed Epiweb v 4.10
- GLP compliance:
- no
- Details on estimation of bioconcentration:
- A regression-based estimate was performed using the specialised chemical estimation software, BCFBAF, version 3.01.
Log Kow used by the BCF estimates: 4.60
Equation used to make BCF estimate:
Log BCF= 0.6598 log kow - 0.333 + correction
Correction(s): alkyl chains (8+ -CH2- groups), value: -1.374 - Type:
- BCF
- Value:
- 21.27 L/kg
- Remarks on result:
- other: wet-wt
- Conclusions:
- The bioconcentration factor of the test item was determined using the specialised chemical estimation software, BCFBAF, version 3.01. The log BCF (regression-based estimate) was calculated as 1.33 (BCF= 21.3 L/kg wet-wt).
Reference
Log BCF (regression-based estimate): 1.33 (BCF= 21.3 L/kg wet-wt).
Description of key information
The bioconcentration factor of the test item was determined using the specialised chemical estimation software, BCFBAF, version 3.01. The log BCF (regression-based estimate) was calculated as 1.33 (BCF= 21.3 L/kg wet-wt).
Key value for chemical safety assessment
- BCF (aquatic species):
- 21.27 L/kg ww
Additional information
The bioaccumulation factor of the test item was determined using the validated computer program BCFBAF v3.00 accessed via Epiweb v4.10. The log BCF (regression-based estimate) was calculated as 1.33 (BCF= 21.3 L/kg wet-wt).
