A chemical compound used as a medicine to prevent urinary tract infections and in the production of rubber.
The doctor prescribed methenamine to help treat her urinary tract infection.
Methenamine is formed from "methen" (a variant of "methene", meaning a type of hydrocarbon) and "amine" (from Latin "aminum", meaning nitrogen-containing compound). The word refers to a compound that contains both a methylene group and an amine group, indicating its chemical structure.
Think of 'methen' as relating to a specific type of hydrocarbon and 'amine' as a nitrogen compound, which together describe a chemical compound that includes both elements.
