DNP Chemical Properties,Usage,Production

Description

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.

Chemical Properties

white to light yellow crystal powde

Uses

2,4-Dinitrophenylhydrazine is known was Brady's reagent, a substituted hydrazine that is often used for qualitative testing of carbonyl groups associated with aldehydes and ketones.

Definition

ChEBI: A C-nitro compound that is phenylhydrazine substituted at the 2- and 4-positions by nitro groups.

Purification Methods

Crystallise DNPH from butan-1-ol, dioxane, EtOH, *C6H6 or EtOAc. The hydrochloride has m 186o (dec). [Beilstein 15 IV 380.]
