Clear colorless to peach liquid | [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. | [Uses]
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. |
