Heterocyclic chemistry is the branch of organic chemistry that focuses on the study of cyclic compounds containing at least one non-carbon atom in the ring structure. These heterocyclic compounds often exhibit unique properties and have a wide range of applications in various industries, including pharmaceuticals, agrochemicals, and materials science. Research in heterocyclic chemistry involves the synthesis, characterization, and study of the reactivity of these compounds, as well as the development of new methods for their preparation. The field plays a crucial role in the discovery and development of new drugs and other important molecules.
