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. See more It can be prepared by the reaction of hydrazine sulfate with 2,4-dinitrochlorobenzene: See more DNPH is a reagent in instructional laboratories on qualitative organic analysis. Brady's reagent or Borche's reagent, is prepared by … See more • Tollens' reagent • Fehling's reagent • Schiff test See more Dry DNPH is friction and shock sensitive. For this reason, it’s supplied damp or ‘wetted’ when a school purchases it from a chemical supplier. If DNPH is stored improperly and left to dry out, it can become explosive. It is artificial uncoupler of electron … See more WebJun 15, 2024 · DNPH is used to detect any carbonyl group (-CO) present in the organic compound. If an aldehyde or ketone is present a yellow, an orange or reddish-orange precipitate of the dinitrophenylhydrazine appears. When these compounds are brought to their melting point, this confirms the carbonyl compound. rocket league download gratis il gioco
