Comments
Teratogenicity observed in mice orally administered 225 mg/kg/day during organogenesis (maternally toxic); [Shepard's Catalog of Teratogenic Agents] A modified local lymph node assay (LLNA) of mice could not be completed due to high dermal toxicity, causing mortality at 60% (approximately 1,570 mg/kg) and 30% (approximately 815 mg/kg) concentrations; Oral LD50 (rat) = 300-500 mg/kg; [EPA - TSCATS] A skin, eye, and respiratory tract irritant; [NTP] A skin and strong eye irritant; Toxic by ingestion; [Sigma-Aldrich MSDS] See "1-Methylimidazole."
