CAS 119-26-6: (2,4-Dinitrophenyl)hydrazine

Description: (2,4-Dinitrophenyl)hydrazine, commonly referred to as DNPH, is an organic compound with the formula C6H6N4O4. It is characterized by its bright yellow crystalline appearance and is primarily used as a reagent for the detection and quantification of carbonyl compounds, such as aldehydes and ketones, through the formation of hydrazones. DNPH is known for its high reactivity due to the presence of two nitro groups, which enhance its electrophilic character. This compound is soluble in organic solvents like ethanol and acetone but has limited solubility in water. It is important to handle DNPH with care, as it is considered hazardous; it can be toxic and potentially explosive when dry. In laboratory settings, DNPH is often utilized in analytical chemistry for the derivatization of carbonyl compounds, facilitating their identification and analysis through techniques such as chromatography. Proper safety measures, including the use of personal protective equipment, are essential when working with this substance.
