Sign in to saveAlso known as Brady's reagent, 2,4-DNP hydrazine, 1-Hydrazino-2,4-dinitrobenzene, 2,4-Dnph
2,4-Dinitrophenylhydrazine (2,4-DNPH or DNPH) is the organic compound C6H3(NO2)2NHNH2. DNPH is a red to orange solid. It is a substituted hydrazine. The solid is relatively sensitive to shock and friction. For this reason DNPH is usually handled as a wet powder. DNPH is a precursor to the drug Sivifene.
