What is N-METHYLURETHANE?

Chemical properties

Clear colorless to peach liquid

The Uses of N-METHYLURETHANE

N-Methylurethan is a byproduct in the synthesis of 3,5-Dimethyl-4-(methylthio)phenol (D474810), which is used as an insecticide and used the synthesis of methiocarb.

General Description

Clear colorless liquid.

Air & Water Reactions

Water soluble.

Reactivity Profile

N-METHYLURETHANE is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Health Hazard

ACUTE/CHRONIC HAZARDS: N-METHYLURETHANE may be narcotic in high concentrations. When heated to decomposition it emits toxic fumes.

Fire Hazard

N-METHYLURETHANE is combustible.

Safety Profile

Moderately toxic by SYNS: 2-BUTANONE, OXIME 0 ETHYL METHYL subcutaneous route. Experimental teratogenic effects. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.See also CARBAMATES.
