The International Union of Pure and Applied Chemistry widely accepted three nomenclatures are the Hantzsch–Widman nomenclature, common names/trivial names, and the replacement nomenclature. The heterocyclic compounds are named by combining suitable prefix, stem, and suffix. The stem indicates the ring ...
