What is a Hexamethylenetetramine?

Hexamethylenetetramine (chemical formula: C₆H₁₂N₄), also known as methenamine or urotropine, is a white crystalline solid with a characteristic odor, synthesized from the reaction of formaldehyde and ammonia. It is used in a variety of applications, including medicine, resins, explosives, and disinfectants. Medically, it is utilized as a urinary antiseptic, where it decomposes in acidic environments to release formaldehyde, which provides antibacterial effects. It is also employed as a hardening agent in plastics and resins, and serves as a precursor in the manufacture of explosives such as RDX.

Hexamethylenetetramine is water-soluble and relatively stable, but under acidic conditions, it can release formaldehyde, which may irritate the respiratory tract and mucous membranes if inhaled or ingested. Proper handling with adequate ventilation and protective measures is necessary.
