Materials and methods

Principles of method if other than guideline:
BASF test
The study was conducted according to an internal BASF method which in principle is comparable to the OECD Guideline 401.
A test group consisting of 5 animals/sex was treated by single gavage with an aqueous solution of the test substance.
The animals were observed for mortality and for clinical symptoms of toxicity. At the end of the observation period, the surviving animals were sacrificed for the purpose of necropsy; animals that died during the observations period also were subjected to necropsy.

The LD50 value was estimated on the basis of the observed mortalities.
GLP compliance:
no
Test type:
standard acute method
Limit test:
no
