Phenmedipham Specification
Reactivity Profile: 3-((Methoxycarbonyl)amino)phenyl (3-methylphenyl)carbamate 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. 3-((Methoxycarbonyl)amino)phenyl (3-methylphenyl)carbamate is incompatible with alkaline preparations.
Fire Hazard: Flash point data for 3-((Methoxycarbonyl)amino)phenyl (3-methylphenyl)carbamate are not available, however 3-((Methoxycarbonyl)amino)phenyl (3-methylphenyl)carbamate is probably combustible.
