- Dose descriptor:
- LD50
- Effect level:
- > 450 - < 1 000 mg/kg bw
- Based on:

- Mortality:
- 1000 mg/kg-day: All rats were euthanized between days 2 and 4 due to moribund condition. 450 mg/kg-day: All animals survived. 150 mg/kg-day: All animals survived.

- 1000 mg/kg-day: Macroscopic examination revealed: gastrointestinal tract distended with gas (all animals), reduced size of the spleen and thymus (2 animals), thickened and pale discolored liver with accentuated lobular pattern (1 animal), and enlarged adrenal glands (1 animal). 450 mg/kg-day: Macroscopic examination revealed: gastrointestinal tract distended with gas (all animals) and reduced size of the spleen and/or thymus (2 animals). One animal had a slightly lower liver weight. Other liver and kidney weights were normal. 150 mg/kg-day: Macroscopic examination revealed: gastrointestinal tract distended with gas (all animals), red discoloration of mesenteric lymph nodes (1 animal), and reduced size of the spleen (1 animal). Liver and kidney weights were normal.

- Toxicity Category IV
- Remarks:

- Executive summary:
The oral toxicity of the test article was (clear, colorless liquid; CASRN 84650-68-0, purity 98.5%; Lot 4, with spikes) was evaluated in Wistar rats in order to determine appropriate doses for a 28-day subacute study. This study was performed under OECD GLP (1997) conditions. Female rats (3/group) received 150, 450, or 1000 mg/kg-day of the test article by oral gavage for 5 days. After the last dose, all surviving animals were euthanized, and macroscopic examinations were performed. Body weights and clinical observations were recorded. Kidney and liver weights were recorded. 1000 mg/kg-day: All rats were euthanized between days 2 and 4 due to moribund condition. The following clinical observations were noted in all rats: lethargy, flat/hunched posture, abnormal gait, labored respiration, piloerection, diarrhea, brown staining of genital region, pale, hypothermia, and/or abdominal swelling. Macroscopic examination revealed: gastrointestinal tract distended with gas (all animals), reduced size of the spleen and thymus (2 animals), thickened and pale discolored liver with accentuated lobular pattern (1 animal), and enlarged adrenal glands (1 animal). 450 mg/kg-day: All animals survived. Reduced food consumption was observed, and all animals lost up to 21% of their body weights. The following clinical observations were noted in all rats: lethargy, hunched posture, piloerection, diarrhea, brown staining of genital region, lean appearance, and abdominal swelling (1 animal). Macroscopic examination revealed: gastrointestinal tract distended with gas (all animals) and reduced size of the spleen and/or thymus (2 animals). One animal had a slightly lower liver weight. Other liver and kidney weights were normal. 150 mg/kg-day: All animals survived. Reduced food consumption was observed, and all animals lost up to 20% of their body weights. The following clinical observations were noted in all rats: hunched posture, piloerection, and diarrhea. Macroscopic examination revealed: gastrointestinal tract distended with gas (all animals), red discoloration of mesenteric lymph nodes (1 animal), and reduced size of the spleen (1 animal). Liver and kidney weights were normal. The 5-day oral LD50 of the test article is greater than 450 mg/kg-day but less than 1000 mg/kg-day.
