In chemistry, the fluoropyridines form a group of organic compounds that belong to the heterocycles (more precisely: heteroaromatics ). They consist of a pyridine ring that is substituted with fluorine  (−F). Its different arrangement results in three constitutional isomers with the empirical formula C ₅ H ₄ FN.
