Heterocycles - Alfa Aesar

Cyclic compounds, which contain atoms from at least two different elements in the ring, are called heterocyclic compounds or simply heterocycles. Most of the heterocycles contain one or more carbon atoms. On the basis of electronic structure, heterocycles could be classified as aromatic, saturated and unsaturated. When the heteroatom forms a part of an aromatic ring, the compound is referred to as an aromatic heterocyclic compound or an aromatic heterocycle. Aromatic heterocycles are classified into single ring heterocycles and condensed ring heterocycles. The single ring heterocycles include, but are not limited to, pyrrole, furan, thiophene, pyridine, etc., and condensed ring heterocylces include, but not limited to, indole, quinoline, and isoquionoline.
