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.
