Hexamine, also known as hexamethylenetetramine, is a crystalline organic compound with the chemical formula (CH2)6N4. It is highly stable and widely used in various industrial applications, including as a precursor for the synthesis of other chemicals like plastics, pharmaceuticals, and explosives. Hexamine is notable for its ability to release formaldehyde when heated, making it valuable in resin and rubber production as a cross-linking agent. Additionally, it serves as a corrosion inhibitor in water treatment and as a component in fuel tablets for camping stoves and military rations due to its clean-burning properties.
