Formula: C₆H₆N₄O₄ or C₆H₃(NO₂)₂NHNH₂ 2,4-Dinitrophenylhydrazine (DNPH) is a red-orange organic compound used as a reagent to detect aldehydes and ketones. It reacts with the carbonyl group (C=O) to form a colored hydrazone precipitate, typically yellow, orange, or red, indicating the presence of a carbonyl compound. DNPH is a substituted hydrazine derivative and is sold commercially as a wet powder for safety, as the dry solid is sensitive to shock and friction.
