| 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.
