Used in the synthesis of pharmaceutical intermediates, particularly in the development of bioactive molecules and heterocyclic compounds. Its aldehyde functional group allows for condensation and nucleophilic addition reactions, making it valuable in constructing complex organic frameworks. Commonly employed in the preparation of agrochemicals, dyes, and fluorescent probes due to its aromatic and electron-rich structure. Also serves as a building block in medicinal chemistry for designing compounds with potential antifungal, anti-inflammatory, or neuroactive properties.
