2,4-dinitrophenylhydrazine, a chemical, English name: 2,4-Dinitrophenylhydrazine, molecular formula: C6H6N4O4. Appearance and properties: red powder. Fire extinguishing agent: water spray, dry powder, foam or carbon dioxide fire extinguishing agent. Avoid the use of direct-current water extinguishing, direct-current water may lead to the splash of flammable liquids, so that the fire spread. A chromogenic reagent for the determination of aldehydes and ketones by spectrophotometry is developed. The chromogenic reagent for aldehydes and ketones is determined by TLC. It is also used as an ultraviolet derivative reagent for aldehydes and ketones for organic synthesis and explosive manufacturing.
