2,4-Dinitrophenylhydrazine Hydrochloride is a reagent used for labeling biomolecules in HPLC. The reaction time is dependent on the specific molecule and the concentration of reactants. 2,4-Dinitrophenylhydrazine Hydrochloride reacts with carbohydrates and other large molecules to form a hydrazone link. This link can be cleaved by heat or acid to release the labeled molecule. It is also used for labeling oligonucleotides, amino acids, and other small molecules that are not amenable for enzymatic reactions. This reagent has been shown to be useful in determining the molecular weights of anions such as chloride or crystallography. The red shift observed during this reaction is due to the interaction energies between water molecules and chloride ions or dimethylformamide molecules.
