Materials and methods

Test guideline
Qualifier:
according to
Guideline:
EU Method A.6 (Water Solubility)
Deviations:
yes
Remarks:
The test substance had to be protected with argon atmosphere and that is why preliminary test was not performed. The value of solubility of the test substance was used from TSDS.
GLP compliance:
no
Type of method:
flask method
