Tropolone is not a substance that is heterocyclic aromatic. Heterocyclic compounds are cyclic structures with two or more different atom types arranged in a ring. This research focuses on organic heterocyclic compounds with at least one carbon atom in each ring. Heteroatoms are any atoms other than carbon that are present. The ring element with the greatest frequency in heterocyclic compounds is still carbon. However, as time passed, heteroatoms in the rings of recognized compounds became more numerous and varied. As a result, the expanding field of inorganic heterocyclic systems is in continual change.

The Heterocyclic compounds are widely distributed in nature and essential to life; they play an important role in all living cells’ metabolism. For instance, these are heterocyclic: the purine and pyrimidine bases of DNA and RNA; these are the three essential amino acids (proline, tryptophan, and histidine); there are several vitamins and coenzyme precursors (riboflavin, thiamine, pyridoxine, biotin, folic acid, and the B12 and E families of vitamins); the oxygen-transporting pigment hemoglobin and its breakdown products, the photosynthesizing pigment chlorophyll; many hormones; the bile pigments; (kinetin, serotonin, heteroauxin, and histamine); and most sugars.
