Applicant's summary and conclusion

Interpretation of results:
Category 3 based on GHS criteria
Conclusions:
These old data showed that SCH may be very toxic when administered acutely to rats and mice via oral, intraperitoneal, subcutaneous and intravenous routes.
All the value obtained for the LD50 are around 100mg/kg, the test item is therefore classify as Category 3 based on the GHS criteria.
