Applicant's summary and conclusion

Interpretation of results:
Category 1 based on GHS criteria
Conclusions:
The acute inhalation toxicity dose LC50 value was considered to be 38.5 mg/m3, when rats were treated with the given test chemical via inhalation route for 4-hour exposure.
Executive summary:

Acute inhalation toxicity study of the given test chemical was conducted in rats at the dose concentration of 38.5 mg/m3 via inhalation route for 4-hour exposure. The animals were observed for clinical signs and mortality. 50% mortality was observed. Increased relative liver weight, pulmonary oedema and marked irritation of the mucous membranes were seen. Therefore, LC50 value was considered to be 38.5 mg/m3, when rats were treated with test chemical via inhalation route for 4-hour exposure.
