Application: 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.

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
