Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its fused heterocyclic structure enhances binding affinity to specific enzyme targets, making it valuable in designing drugs that modulate cell signaling pathways. Also explored in agrochemicals for creating novel pesticides due to its ability to interact with biological receptors in pests. The carboxylic acid group allows for easy derivatization, enabling the formation of amides, esters, and other functional groups to optimize compound efficacy and solubility.
