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.

Health Hazard Information Acute Effects: Acute oral exposure to high levels of 2,4-dinitrophenol in humans has resulted in increased basal metabolic rate, nausea, vomiting, sweating, dizziness, headache, loss of weight, and other symptoms. (1,2) 2,4-Dinitrophenol is considered to have high acute toxicity, based on short-term animal tests in rats and mice. (3) Chronic Effects (Noncancer): Chronic oral exposure to 2,4-dinitrophenol in humans and animals has resulted in the formation of cataracts and skin lesions and has caused effects on the bone marrow, CNS, and cardiovascular system. (1,2) The Reference Dose (RfD) for 2,4-dinitrophenol is 0.002 milligrams per kilogram body weight per day (mg/kg/d) based on cataract formation in humans. The RfD is an estimate (with uncertainty spanning perhaps an order of magnitude) of a daily oral exposure to the human population (including sensitive 

 

Chemical properties

2,4-Dinitrophenol is a yellow, crystalline solid that has a sweet, musty odor. It sublimes when carefully heated and is volatile with steam. It is soluble in water (sparingly) (its crystalline sodium salts are also soluble in water), cold water (sparingly), ethyl acetate, acetone, chloroform, pyridine, carbon tetrachloride, toluene, alcohol, benzene, and aqueous alkaline solutions (Merck, 1989). It forms explosive salts with alkalies and ammonia, and emits toxic fumes of nitrogen oxides when heated to decomposition (Sax, 1989). It is incompatible with heavy metals and their compounds.

 

Industrial uses

Commercial DNP is primarily used for scientific research and in manufacturing. It has been used at times to make dyes, other organic chemicals, and wood preservatives. It has also been used to make photographic developer, explosives, and pesticides.

 

How does it work?

2,4-dintrophenol (DNP) helps to move protons across membranes in cells, resulting in a reduction in the production of ATP (adenosine triphosphate, the molecule that transports energy within cells). This means that much of the energy that is usually generated in respiration is instead wasted as heat (which can lead to fatal hyperthermia). The body compensates by increasing its metabolic rate in order to produce the energy needed to maintain the body. This increase in metabolic rate results in the consumption of fat.
