applications

2,4-Dinitrophenol (DNP) can be used:
– As a reactant for catalytic reduction reactions.
– To activate carboxylic acids by converting them into dinitrophenyl (DNP) esters.
– To prepare the corresponding ester via acylation reaction using isobutyric anhydride catalyzed by hafnium triflate.
– As an effective cocatalyst to accelerate the activity and enantioselectivity of primary amine organocatalyst derived from natural primary amino acids for direct asymmetric aldol reaction.
– As an alternative activator to tetrazoles in the reaction of phosphoroamidites with nucleosides.
