| | N-Methyl-4-nitroaniline Usage And Synthesis |
| Uses | N-methyl-4-nitroaniline is a stabilizer for gunpowder, a desensitizing agent for molten cast explosive TNAZ, a widely used organic intermediate, and N-methyl-4-nitroaniline can be used as a reference substance by its polarizing properties.
N-methyl-4-nitroaniline is an attractive candidate for its appealing capability to retain the nitrogen oxides, good thermal stability, and facile synthesis from abundant and inexpensive starting materials.
| | Biodegradation | N-Methyl-4-nitroaniline is used as an additive to lower the melting temperature of energetic materials in the synthesis of insensitive explosives. Although the biotransformation of N-Methyl-4-nitroaniline under anaerobic condition has been reported, its aerobic microbial degradation has not been documented yet. A soil microcosms study showed the efficient aerobic degradation of N-Methyl-4-nitroaniline by the inhabitant soil microorganisms.
| | Chemical Properties | brownish-yellow crystalline powder | | Uses | N-Methyl-4-nitroaniline is a versatile reactant used in the synthesis of oxindoles using Pd-catalyzed cyclization of chloroacetanilides. | | General Description | Brownish-yellow prisms with violet reflex (from ethanol) or yellow powder. | | Air & Water Reactions | N-Methyl-4-nitroaniline may be sensitive to prolonged exposure to air. Insoluble in water. | | Reactivity Profile | N-Methyl-4-nitroaniline has a vigorous exothermic reaction with carbaryl sulfate when heated above 167° F. | | Fire Hazard | Flash point data for N-Methyl-4-nitroaniline are not available; however, N-Methyl-4-nitroaniline is probably combustible. | | Purification Methods | Crystallise the aniline from aqueous EtOH.
