The substance; 2, 4-Dinitrophenol has many other brand names such as, 1 Hydroxy-2,4-dinitrophenol, Solfo Black, Nitrophen, Aldifen, and Chemox are just a few and is among many things, a metabolic stimulant. That is it's popularity here in our world, it burns fat like no other. Let me just tell you of it's other uses before I continue. First, it is a toxic dye, chemically related to Trinitrophenol (Picric Acid), second, it is found in insecticides, wood preservatives, herbicides, explosives, and is also a hazardous material. Third, it is used in science to couple or attach to DNA molecules. All of this should tell you that it is not a run-of-the-mill metabolic stimulant, like Clenbuterol or Triacana or Ephedrine or any other for that matter. Here is DNP's tox faq's from the international chemical safety cards to you give an idea of what it is considered to be; Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion. DO NOT expose to friction or shock. MAY BE ABSORBED! Redness. Roughness. Yellow staining on the skin. PHYSICAL STATE; APPEARANCE: YELLOW CRYSTALS ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. CHEMICAL DANGERS: May explosively decompose on shock, friction, or concussion. May explode on heating. Shock-sensitive compounds are formed with alkalis, ammonia and most metals. The substance decomposes on heating producing toxic gases including nitrogen oxides. EFFECT OF SHORT-TERM EXPOSURE: The substance may cause effects on metabolism, resulting in very high body temperature. Exposure may result in death. EFFECTS OF LONG TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the peripheral nervous system. The substance may have effects on the eyes, resulting in cataracts. Boiling point: sublimes °C, Melting point: 112°C, Relative density (water = 1): 1.68. Solubility in water, g/100 ml at 54.5°C: 0.14. Relative vapor density (air = 1): 6.36. This product is handled and shipped in a 15% solution of water, making it a paste, so that it will not explode due to shock or friction.
