*This document is like a lab demo—an example Certificate of Analysis (COA) that showcases what a COA looks like but may not match the latest batch in all its glory. Think of it as a chemistry experiment: close, but not quite the final reaction!

| hazards summary | 1,2-Epoxybutane is primarily used as a stabilizer in chlorinated hydrocarbon solvents. No information is available on the acute (short-term), chronic (long-term), reproductive, developmental, or carcinogenic effects of 1,2-epoxybutane in humans. Irritation and inflammation of the nasal passageways, lungs, and skin have been observed in animal studies following acute inhalation and dermal exposures. Chronic inhalation exposure of rats and mice to 1,2-epoxybutane causes degenerative lesions of the nasal cavity. In a National Toxicology Program (NTP) study, tumors of the nasal cavity and alveolar/bronchial tumors were produced in rats, while no tumors were observed in mice. The International Agency for Research on Cancer (IARC) has classified 1,2-epoxybutane as a Group 2B, possibly carcinogenic to humans.A skin, eye, and respiratory tract irritant. Inhalation of high concentrations can cause CNS depression. Danger of cutaneous absorption. Toxic by inhalation at room temperature. Liquid or vapor can burn eyes. May cause skin sensitization. A corrosive substance that can cause injury to the skin, eyes, and respiratory tract. Inhalation may cause chemical pneumonitis and pulmonary edema. No data available on human exposure to the pure substance. 1,2-Butylene oxide, stabilized (UN3022) has warning of explosive polymerization. See Ethylene oxide. |
