Phenolic molecules are a diverse group of organic materials characterized by the presence of a hydroxyl -OH group directly attached to an aromatic structure. This unique structural feature imparts distinctive attributes to these compounds, making them prevalent in various natural and synthetic environments. The aromatic ring often consists of a benzene core but can also incorporate other heterocyclic fragments.
The position of the hydroxyl group relative to the aromatic nucleus significantly influences the biological properties of phenolic substances. Factors like dissolution, responsiveness, and durability are heavily influenced by this configuration.
