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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- No data
Constituent 1
Sampling and analysis
- Details on sampling:
- No data
Test solutions
- Vehicle:
- not specified
- Details on preparation of test solutions, spiked fish food or sediment:
- No data
Test organisms
- Test organisms (species):
- no data
- Details on test organisms:
- No data
Study design
- Route of exposure:
- other: no data
- Test type:
- not specified
- Water / sediment media type:
- not specified
Test conditions
- Hardness:
- No data
- Test temperature:
- No data
- pH:
- No data
- Dissolved oxygen:
- No data
- TOC:
- No data
- Salinity:
- No data
- Details on test conditions:
- No data
- Nominal and measured concentrations:
- No data
- Reference substance (positive control):
- not specified
- Details on estimation of bioconcentration:
- Based upon a water solubility of 25400 mg/L at 25 degrees Centigrade the calculated bioconcentration factor of 2 indicates that environmental accumulation is unlikely. This BCF value suggests that bioconcentration in aquatic organisms is not important.
