Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Test guidelineopen allclose all
Qualifier:
according to guideline
Guideline:
OECD Guideline 105 (Water Solubility)
Deviations:

Qualifier:
according to guideline
Guideline:
EU Method A.6 (Water Solubility)
Deviations:
yes
Remarks:
see below
Principles of method if other than guideline:
The guideline specifies that the test item in excess should be added to water however the very high water solubility of the test item do not permit this due to technical feasibility reasons. The study method therefore deviates from the guideline but is considered scientifically valid.
GLP compliance:
yes
Type of method:
flask method
