CAS 51-28-5: 2,4-Dinitrophenol

Description: 2,4-Dinitrophenol (DNP) is an organic compound with the molecular formula C6H4N2O5. It is characterized by its yellow crystalline appearance and is known for its strong acidic properties, with a pKa around 4.1. DNP is a nitrophenol derivative, featuring two nitro groups (-NO2) positioned at the 2 and 4 carbon atoms of the phenolic ring. This compound is highly soluble in organic solvents and exhibits moderate solubility in water. DNP is primarily recognized for its role as a metabolic uncoupler, disrupting ATP synthesis in cellular respiration, which has led to its controversial use in weight loss and bodybuilding, despite significant health risks. It is also utilized in various industrial applications, including as a pesticide and in the synthesis of dyes and explosives. However, due to its toxicity and potential for causing severe health issues, including hyperthermia and organ failure, its use is heavily regulated in many countries. Safety precautions are essential when handling this compound due to its hazardous nature.
