Materials and methods

Principles of method if other than guideline:

To estimate the LD50 value, mice were administered the test substance intraperitoneally and kept for observation for 7 days. A solution of the test substance was prepared on a weight/volume basis. The concentrations were varied to allow administration of a constant volume of 0.015 mL/g bw.

GLP compliance:

no

Remarks:

performed prior to GLP

Limit test:

no
