2,4-Dinitrophenol (2,4-DNP or just DNP) is a natural compound with the formula HOC6H3(NO2)2. It is a yellow, crystalline strong that has a sweet, moldy smell. It sublimes, is unpredictable with steam, and is soluble in a lot of organic solvents in addition to liquid alkaline services. When in a dry type, it is a high dynamite and has an instantaneous rise risk. It is a precursor to other chemicals and is biochemically active, preventing adenosine triphosphate (ATP) production in cells with mitochondria.

Commercially, DNP is made use of as an antiseptic and as a non-selective bioaccumulating pesticide.

DNP is especially advantageous as a herbicide together with other thoroughly related dinitrophenol herbicides like 2,4-dinitro-o-cresol (DNOC), dinoseb and dinoterb. Considered that 1998 DNP was withdrawn from agricultural usage. Currently, there are no actively signed up pesticides including DNP in US or Europe.

It is a chemical intermediate in the production of sulfur dyes, wood preservatives and picric acid. DNP has similarly been utilized to make photographic developers and dynamites. DNP is categorized as a dynamite in the UK and USA.

In living cells, DNP functions as a proton ionophore, a representative that can shuttle bus protons (hydrogen cations) throughout biological membranes. It dissipates the proton gradient across mitochondria and chloroplast membranes, collapsing the proton motive force that the cell utilizes to produce the majority of its ATP chemical energy. Instead of producing ATP, the energy of the proton gradient is lost as heat.

DNP acts as a protonophore, allowing protons to leakage across the inner mitochondrial membrane and hence bypass ATP synthase. This makes ATP energy production less effective. In effect, part of the energy that is typically produced from cellular respiration is wasted as heat. The ineffectiveness is proportional to the dosage of DNP that is taken. As the dose increases and energy production is made more inefficient, metabolic rate increases (and more fat is burned) in order to compensate for the inadequacy and to satisfy energy needs. DNP is more than likely the very best understood representative for uncoupling oxidative phosphorylation. The "phosphorylation" of adenosine diphosphate (ADP) by ATP synthase gets detached or "uncoupled" from oxidation.

"Dinitrophenol uncouples oxidative phosphorylation, triggers release of calcium from mitochondrial stores and avoids calcium re-uptake. This triggers totally free intracellular calcium and activates contraction and hyperthermia. Dantrolene prevents calcium release from the sarcoplasmic reticulum which lessens intracellular calcium. The resulting muscle relaxation permits heat dissipation. There is little threat to dantrolene administration. Due to the fact that dantrolene may operate in reducing hyperthermia caused by representatives that inhibit oxidative phosphorylation, early administration might enhance result.

DNP was commonly made use of in explosive mixtures around the world. Shellite in the UK, Tridite in the United States, Tridita in Spain, MDPC/DD in France, MABT/MBT in Italy, and DNP in the USSR.

Nowadays, DNP is used primarily online under a number of different names such as 'DNP', 'Dinosan', 'Dnoc', 'Solfo Black', 'Nitrophen', 'Aldifen' and 'Chemox'. The chemical is a yellow crystalline powder that has a sweet, moldy smell and is soluble in water. The dose of DNP per tablet varies from website to site however it is most frequently offered as either 100- or 200-mg tablets. Some web sites have DNP offered wholesale quantities, permitting users to purchase kilograms of DNP powder or hundreds/thousands of DNP-containing tablets.

DNP has in fact been offered for over a century, at first in the manufacture of munitions, due to its explosive residential or business properties. From the 1930s onwards, there has actually been interest in its homes to increase the underlying metabolic rate, leading to an associated weight-loss. It appears that there has actually been increasing interest and schedule of DNP-containing items on the for sale
