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-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. In humans, DNP causes dose-dependent mitochondrial uncoupling , causing the rapid loss of ATP as heat and leading to uncontrolled hyperthermia —up to 44 °C (111 ...

The first reaction is the formation of the N-2,4-dinitrophenyl-pyridinium salt (2). This salt is typically isolated and purified by recrystallization. The formation of the DNP-pyridinium salt. Upon heating a primary amine with the N-2,4-dinitrophenyl-pyridinium salt (2), the addition

Dinitrophenols are chemical compounds which are nitro derivatives of phenol.. There are six isomers of dinitrophenol: Chemical structure of 2,4-Dinitrophenol. 2,3-Dinitrophenol; 2,4-Dinitrophenol
Diazodinitrophenol (DDNP) was the first diazo compound produced; it was subsequently used to make dyes and explosives. It forms yellow crystals in pure form; however, the color of impure forms may vary from dark yellow to green to dark brown. [1]
