2,4-Dinitrotoluene (DNT) is an aromatic nitro compound primarily used as an intermediate in the synthesis of toluene diisocyanate (TDI), a key reagent in polyurethane production. It also serves as a high-energy explosive precursor and in the manufacture of dyes and pharmaceuticals. This yellow crystalline solid is stable under ambient storage conditions but carries the signal word Danger and is classified as toxic if swallowed, in contact with skin or if inhaled. CAS 121-14-2, molecular formula C7H6N2O4, with a purity typically exceeding 98% for industrial applications. It is hazardous: it is suspected of causing genetic defects, may cause cancer, is suspected of damaging fertility, may cause damage to organs through prolonged or repeated exposure, and is very toxic to aquatic life with long-lasting effects. It requires dry storage to prevent moisture absorption. Molekula supplies 2,4-Dinitrotoluene from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
