    en.wikipedia.org/wiki/2,4-Dinitrophenylhydrazine

    2,4-Dinitrophenylhydrazine (2,4-DNPH or DNPH) is the organic compound C 6 H 3 (NO 2) 2 NHNH 2. 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.

    R 2 C=N−NR' 2 + H 2 O → R 2 C=O + H 2 N−NR' 2. Alkyl hydrazones are 10 2 - to 10 3-fold more sensitive to hydrolysis than analogous oximes. [10] When derived from hydrazine itself, hydrazones condense with a second equivalent of a carbonyl to give azines: [11] R 2 C=N−NH 2 + R 2 C=O → R 2 C=N−N=CR 2 + H 2 O. Hydrazones are ...
