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 characteristic imparts distinctive attributes to these molecules, making them prevalent in various natural and synthetic environments. The aromatic ring often consists of a benzene core but can also feature other heterocyclic moieties.

The placement of the hydroxyl group relative to the aromatic nucleus significantly influences the biological properties of phenolic molecules. Factors like solubility, interaction, and resistance are affected by this arrangement.
