Phenolic compounds are a diverse group of organic structures characterized by the presence of a hydroxyl -OH group directly attached to an aromatic structure. This unique structural element imparts distinctive attributes to these compounds, making them prevalent in various natural and synthetic systems. The aromatic ring often consists of a benzene nucleus but can also incorporate other heterocyclic moieties.
The placement of the hydroxyl group relative to the aromatic nucleus significantly influences the physical properties of phenolic molecules. Factors like solubility, responsiveness, and durability are affected by this disposition.
Exploring the Bioactive Potential of Phenols
