Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its aldehyde functional group allows for easy derivatization, enabling the formation of imines, oximes, or alcohols, which are valuable in drug design. Commonly employed in medicinal chemistry for constructing heterocyclic scaffolds with potential anti-inflammatory, anticancer, or central nervous system activity. Also utilized in research settings for generating compound libraries in structure-activity relationship (SAR) studies.
