What is METHANESULFONYL FLUORIDE?
Chemical properties
clear colorless to yellow liquid
General Description
Liquid.
Air & Water Reactions
On contact with moisture METHANESULFONYL FLUORIDE produces highly corrosive and toxic fumes of hydrogen fluoride gas.
Reactivity Profile
METHANESULFONYL FLUORIDE is corrosive, toxic liquid. Vigorous reaction with water, steam, alkali. A dangerous storage hazard. On contact with moisture METHANESULFONYL FLUORIDE produces highly corrosive and toxic fumes of hydrogen fluoride gas. When heated to decomposition METHANESULFONYL FLUORIDE emits toxic fumes of fluoride, and oxides of sulfur [M. K.]. 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
Highly toxic when inhaled.
Fire Hazard
When heated to decomposition, METHANESULFONYL FLUORIDE emits very toxic fumes of fluorides and sulfur oxides.
