DNP Usage And Synthesis
2,4-Dinitrophenylhydrazine (abbreviated 2,4-DNP for short) is the chemical compound C6H3 (NO2) 2NHNH2, and it is often used to qualitatively test for carbonyl groups associated with aldehydes and ketones. The hydrazone derivatives can also be used as evidence toward the identity of the original compound. It is relatively sensitive to shock and friction; it is a shock explosive, so care must be taken with its use. To reduce its explosive hazard, it is usually supplied wet.
2,4-Dinitrophenylhydrazine is a compound with a benzene ring, two Nitro groups, and a hydrazine (two nitrogen atoms bonded directly to each other) functional group. It is used as a Brady's reagent to test the existing of a ketone or aldehyde.
