Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting cancer-related enzymes. Its aldehyde functional group allows for easy modification, enabling the formation of imines, alcohols, or carboxylic acid derivatives used in drug development. Also employed in the preparation of fluorescent probes due to its heteroaromatic structure, which can enhance photophysical properties in sensing applications. Commonly found in medicinal chemistry workflows for building complex nitrogen-containing scaffolds with biological activity.
