Hexamethylenetetramine, also known as methenamine, is a raw material for organic synthesis and is used to produce chloramphenicol in the pharmaceutical industry. Hexamethylenetetramine can be used as a disinfectant for the urinary system. It has no antibacterial effect itself and is effective against Gram-negative bacteria. Its 20% solution can be used to treat underarm odor, sweaty feet, tinea corporis, etc. It can be mixed with sodium hydroxide and sodium phenol to be a phosgene absorber in gas masks. It is used to make pesticides and insecticides. Hexamethylenetetramine reacts with fuming nitric acid to produce highly explosive cyclone explosives, referred to as RDX. Hexamethylenetetramine can also be used as a reagent for the determination of bismuth, indium, manganese, cobalt, thorium, platinum, magnesium, lithium, copper, uranium, beryllium, tellurium, bromide, iodide, etc. and a chromatographic analysis reagent. It is a commonly used military fuel.
