- Sex:
- male
- Details on test animals or test system and environmental conditions:
- Weight at study initiation: 90 -120g
Fasting period before study: No fasting
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- not specified
- Details on oral exposure:
- VEHICLE
Concentration in vehicle: 3250 mg/kg
Amount of vehicle (if gavage): 1 ml to 10 ml
CLASS METHOD (if applicable)
Rationale for the selection of the starting dose:
Doses were given in a logarithmic series differing by a factor of 2. - Doses:
- 3250 mg/kg bw
- No. of animals per sex per dose:
- 5 male
- Control animals:
- not specified
- Details on study design:
- - Duration of observation period following administration: 14 days
- Statistics:
- The most probable LD50 value and its fiducial range are estimated by the method of Thompson, using the Tables of Weil. The figures in parentheses show limits of ± 1.96 standard deviations while the absence of parentheses indicates that no range is calculable because no dosage resulted in fractional mortality

Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- LD50 was considered to be 3250 mg/kg bw when Carworth Wistar male rat were treated with 3'-Nitroacetophenone orally by gavage
- Executive summary:
In a Acute oral toxicity study, 5 Carworth Wistar male rats were treated with 3'-Nitroacetophenone in the concentration of 3250 mg/kg bw orally by gavage and observed for 14 days. 50 % mortality was observed in treated rats at 3250 mg/kg bw after 14 days. Therefore, LD50 was considered to be 3250 mg/kg bw when Carworth Wistar male rat were treated with 3'-Nitroacetophenone orally by gavage.
