Formaldehyde 2,4-Dinitrophenylhydrazone

Formaldehyde 2,4-Dinitrophenylhydrazone, also known as DNPH, is a chemical compound that is commonly used in the detection and quantification of aldehydes and ketones in various biological and environmental samples. It is a yellow, crystalline powder that is soluble in most organic solvents and has a melting point of 214-216°C. DNPH is commonly used in analytical chemistry as a reagent to detect the presence of carbonyl groups in organic compounds. It forms a bright yellow-orange precipitate with aldehydes and ketones, which can be easily quantified using spectrophotometric methods. This reagent is often employed in the analysis of air pollutants, food additives, and pharmaceuticals. In addition to its analytical applications, DNPH has also been used in the synthesis of various organic compounds, including dyes, pharmaceuticals, and explosives. However, it is important to note that DNPH is a hazardous substance and should be handled with care. It can cause skin and eye irritation, and inhalation of its vapors can cause respiratory distress. Overall, DNPH is a useful tool in the detection and quantification of aldehydes and ketones in various samples. Its versatility and reliability make it a valuable asset in the fields of analytical chemistry, environmental science, and pharmaceuticals.
