Applications

Nitromethane is used as a stabilizer of halogenated organic solvents, rocket and racing fuel and a chemical intermediate. It is also used as a solvent for cyanoacrylate adhesives, polymers and waxes. It serves as a Michael donor, adding to alfa,beta-unsaturated carbonyl compounds through 1,4-addition in the Michael reaction. It acts as a solvent used for extractions, reaction medium and as a cleaning solvent. Further, it is used in the manufacture of pharmaceuticals, explosives, fibers and coatings.

Notes

Incompatible with amines, strong acids, strong bases, strong oxidizing agents, strong reducing agents and copper
