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