Butyl chloroformate Usage And Synthesis

Chemical Properties	clear liquid
Uses	Butyl Chloroformate is a reactant in the preparation of Lapatinib derivatives as HER1/HER2 targeting antitumor drugs.
General Description	A colorless liquid. Flash point near 70°F. Very toxic by inhalation. Denser than water. Used to make other chemicals.
Air & Water Reactions	Highly flammable. Decomposes exothermically in water to give hydrochloric acid and organic acids.
Reactivity Profile	Butyl chloroformate is incompatible with bases (including amines), with water, with strong oxidizing agents, with alcohols. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
Health Hazard	Inhalation of vapor irritates nose and throat and can cause delayed pulmonary edema. Liquid irritates eyes and causes severe skin burns and irreversible skin damage if allowed to remain. Can cause blindness. Ingestion causes burns of mouth and stomach.
Flammability and Explosibility	Flammable
