Overview
Nitromethane (CAS 75-52-5 ), also referenced in shorthand as MeNO2, is a high-polarity solvent and reactive chemical intermediate used across pharmaceutical synthesis and specialty fuel applications.
Its ability to dissolve a broad range of organic and inorganic compounds makes it a preferred solvent where conventional options fall short in industrial processes and chemical manufacturing.
In pharmaceutical manufacturing, it functions as a reaction solvent and building block in the synthesis of active pharmaceutical ingredients, particularly where nitroalkane chemistry is required.
The polymer and plastics industry uses it as a solvent for cellulose esters and as a reactive monomer precursor in specialty formulations for various high-performance materials and coatings.
In motorsport, aerospace, and defense sectors, high-purity nitromethane is a primary fuel component and oxidizer in high-performance combustion systems and specialized propulsion technologies.
Metalworking and lubricant formulators use it as a solvent carrier for cleaning agents and surface treatment preparations to ensure high-quality finishes and effective industrial maintenance.
Nitromethane is supplied as a clear liquid in drum, IBC, and bulk tanker quantities. Technical grade is the most common supply form, with high-purity grades available for specialty synthesis.
Buyers should confirm purity specifications, typically 95% to 99%+, based on end-use requirements, as fuel-grade and synthesis-grade material are not always interchangeable for all applications.
