2,4-Dinitrophenylhydrazine, reagent, 97%, 10g CAS Number: 119-26-6 Linear Formula: (O2N)2C6H3NHNH2 Molecular Weight: 198.14 Structural Formula: 2,4-Dinitrophenylhydrazine (DNPH, Brady's reagent) is a substituted hydrazine, and 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. 2,4-Dinitrophenylhydrazine can be used to qualitatively detect the carbonyl functionality of a ketone or aldehyde functional group. A positive test is signaled by a yellow, orange or red precipitate (known as a dinitrophenylhydrazone). If the carbonyl compound is aromatic, then the precipitate will be red; if aliphatic, then the precipitate will have a more yellow color.
