2,4-Dinitrophenol (2,4-DNP or simply DNP) is an organic compound with the formula HOC 6 H 3 (NO 2) 2. It has been used in explosives manufacturing and as a pesticide and herbicide.

2,4-Dinitrophenylhydrazine (2,4-DNPH or DNPH) is the organic compound C 6 H 3 (NO 2) 2 NHNH 2. DNPH is a red to orange solid. It is a substituted hydrazine. The solid is relatively sensitive to shock and friction. For this reason DNPH is usually handled as a wet powder. DNPH is a precursor to the drug Sivifene.

2,4 DNP Test (2,4-Dinitrophenylhydrazine) - 2,4-Dinitrophenylhydrazine (DNPH) is the organic compound C6H3(NO2)2NHNH2. 2,4dinitrophenylhydrazine reacts with both aldehydes and ketones forms a 2,4 dinitrophenylhydrazone. Visit BYJU’S to learn more about it.

There are six different dinitrophenols. The most commercially important dinitrophenol, 2,4-di-nitrophenol (DNP), is a yellow solid with no smell. It is used in making dyes, wood preservatives, explosives, insect control substances, and other chemicals, and as a photographic developer.

An aldehyde reacts with 2,4-dinitrophenylhydrazine to give a bright, yellow-to-orange crystalline solid called a 2,4-dinitrophenylhydrazone (2,4-DNP).

2,4-dinitrophenylhydrazine is a C-nitro compound that is phenylhydrazine substituted at the 2- and 4-positions by nitro groups. It has a role as a reagent. It is a member of phenylhydrazines and a C-nitro compound. C6H6N4O4. Computed by PubChem 2.2 (PubChem release 2021.10.14) Other Uses -> Explosives. Copyright © 2009-2025 John Wiley & Sons, Inc.

The 2,4-DNP Test is used to detect the presence of carbonyl groups in aldehydes and ketones. When a compound containing a carbonyl group (C=O) reacts with 2,4-dinitrophenylhydrazine, it forms a yellow, orange, or red precipitate, known as a 2,4-dinitrophenylhydrazone.

May 13, 2024 · 2,4-Dinitrophenylhydrazine (DNPH) is a organic chemical compound widely used as a reagent in organic chemistry to detect and identify carbonyl molecules, particularly aldehydes and ketones. It has the molecular formula C6H3NHNHCONHNH2.

2,4-DNP has been tested for genotoxicity in several in vivo and numerous in vitro test systems; 2,3-, 2,5-, 2,6-, 3,4-, and 3,5-DNP were tested in vitro for mutagenicity (see Tables 2-6 and 2-7). In vivo studies have evaluated effects on DNA synthesis and clastogenic effects. Regarding effects on DNA synthesis, some chemical mutagens and ...

Concentrations of 2,4-DNP in the needles collected from different areas and of different ages ranged from <3.7 to 33.1 μg/kg (Hinkel et al. 1989). The concentrations of 2,4-DNP were higher in needles obtained from roadside and urban areas than rural areas.
