- Mortality:
- No mortality occurred during this study.
- Clinical signs:
- other: The most notable clinical signs consisted of transient incidences of urine/fecal stains, soft stools and reddish colored urine.
- Gross pathology:
- Internal obervations at necropsy were limited to reddened adrenal glands in one animal.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of this test, the acute oral LD50 of the test substance was determined to be greater than 5000 mg/kg bw in the rat.
