Phenolic substances are a diverse group of organic structures characterized by the presence of a hydroxyl -OH group directly attached to an aromatic ring. This unique structural element imparts distinctive characteristics to these molecules, making them prevalent in various natural and synthetic products. The aromatic ring often consists of a benzene core but can also include other heterocyclic units.
The location of the hydroxyl group relative to the aromatic ring significantly influences the biological properties of phenolic compounds. Factors like dissolution, reactivity, and stability are shaped by this disposition.
