2,4-dinitrotoluene

2,4-Dinitrotoluene (CAS 121-14-2), commonly referenced as 2,4-DNT, is a nitroaromatic compound used primarily as a chemical intermediate in the synthesis of toluenediamine and toluene diisocyanate.

Where is 2,4-dinitrotoluene used?

• Polyurethane production: key precursor
• Propellant formulations: stabilizer and burn rate modifier
• Defense and aerospace: incorporated into smokeless powder
• Solid propellant compositions: regulates combustion characteristics
• Automotive: TDI-based polyurethane foams for seating and insulation
• Hydrogenation pathway yields toluenediamine, the direct precursor to TDI in large-scale manufacturing.

Good to know: Requires careful handling and storage in accordance with safety protocols for nitroaromatic chemicals.

Commercial specifications

• Purity specifications generally align with industrial standards
• Packaging options ranging from drum to IBC depending on regional handling regulations
