Ethanal-2,4-dinitrophenylhydrazone

Description:
Ethanal-2,4-dinitrophenylhydrazone, with the CAS number 1019-57-4, is a chemical compound formed from the reaction of ethanal (acetaldehyde) with 2,4-dinitrophenylhydrazine. This compound is characterized by its bright yellow crystalline appearance, which is a result of the presence of the dinitrophenyl group. It is commonly used in organic chemistry as a derivative for the identification and characterization of aldehydes and ketones through the formation of hydrazones. Ethanal-2,4-dinitrophenylhydrazone is relatively stable under standard conditions but may decompose upon exposure to strong acids or bases. Its melting point and solubility can vary depending on the solvent used, but it is generally soluble in organic solvents such as ethanol and acetone. The compound is also notable for its ability to form a precipitate in the presence of certain reagents, making it useful in analytical chemistry for qualitative analysis. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested.
