HETEROCYCLIC COMPOUNDS (macromolecular compounds C08)

Description

Heterocyclic compounds containing one or more atoms other than carbon in a ring structure, including nitrogen, oxygen, sulfur, phosphorus, and other heteroatoms. This subclass encompasses diverse ring systems ranging from simple five- and six-membered rings (such as pyrroles, furans, thiophenes, and pyridines) to complex polycyclic and fused ring structures. Compounds are classified by ring size, number of heteroatoms, and their position within the ring system, with separate divisions addressing specific chemical properties and synthesis routes. Adjacent subclass C07C covers acyclic and carbocyclic organic compounds, while C07B addresses general methods of organic synthesis applicable across compound classes.
