Acrolein 2,4-Dinitrophenylhydrazone

Acrolein 2,4-Dinitrophenylhydrazone, also known as DNPH-acrolein or Acrolein-DNPH, is a yellow to orange solid that is used in analytical chemistry as a reagent for the detection and analysis of aldehydes and ketones. This compound is a derivative of acrolein, a highly reactive and toxic organic compound that is used in the manufacturing of plastics, pesticides, and other industrial products. In analytical chemistry, DNPH-acrolein is commonly used in the determination of carbonyl compounds in various samples, such as air, water, and food. This compound reacts with aldehydes and ketones to form stable hydrazones, which can be detected and quantified using spectroscopic or chromatographic methods. DNPH-acrolein is particularly useful in the analysis of environmental and occupational samples, where exposure to aldehydes and ketones can be harmful to human health. The chemical formula of DNPH-acrolein is C9H8N4O4, and its molecular weight is 236.18 g/mol. It has a melting point of 192-194°C and is soluble in organic solvents such as acetone, ethanol, and chloroform. This compound is stable under normal conditions but may react with strong oxidizing agents or bases. DNPH-acrolein is considered a hazardous substance and should be handled with care in a well-ventilated area and with appropriate protective equipment.
