Air & Water Reaktionen
Water soluble.
Reaktivität anzeigen
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.
Brandgefahr
N-METHYLURETHANE is combustible.
Sicherheitsprofil
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.
