Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- - Principle of test:
A group of 4 male rats were exposed, whole body, to an atmosphere of 30,000 ppm T-7869 (430 mg/L, vapor) for 4 hours. A second group of 4 rats served as a control group and were exposed to an atmosphere containing no test material.
- Parameters analysed / observed: Observations were made continually during the study. Urine samples were collected every 24 hours for 2 consecutive days post-exposure and analyzed for metabolites via NMR. Body weights were recorded at pre-test, daily, and at termination. After the 14 day observation period, all animals were euthanized and gross necropsy was performed. The organ weights of the liver, kidneys, and testes were recorded. - GLP compliance:
- yes
- Test type:
- fixed concentration procedure
- Limit test:
- yes

- Executive summary:
The acute inhalation toxicity of T-7869 was evaluated in male Sprague Dawley rats. The study method was based on a custom protocol. A group of 4 male rats rats were exposed, whole body, to an atmosphere of 30,000 ppm T-7869 (430 mg/L, vapor) for 4 hours. A second group of 4 rats served as a control group and were exposed to an atmosphere containing no test material. Observations were made continually during the study. Urine samples were collected every 24 hours for 2 consecutive days post-exposure and analyzed for metabolites via NMR. Body weights were recorded at pre-test, daily, and at termination.After the 14 day observation period, all animals were euthanized and gross necropsy was performed. The organ weights of the liver, kidneys, and testes were recorded. All animals survived. There were no abnormal clinical observations, changes in body weight, necropsy findings, or changes in organ weights. There was 20.49 ug (less than 0.0001% of theoretical maximum) of the test material detected in the urine after 24 hours, and none was detected after 48 hours (below the limit of detection), indicating that T-7869 undergoes very limited metabolism. Based on the results of the study, the 4 hour acute inhalation LC50 in male rats was greater than 428 mg/L (vapor) (30,000 ppm) and the test article is not classified for acute inhalation lethality according to GHS.
