Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the formation of biologically active compounds with high selectivity and potency. Commonly employed in medicinal chemistry for constructing heterocyclic scaffolds in drug discovery programs. Also utilized in the preparation of fluorescent probes and dyes due to its favorable photophysical properties. Serves as a building block in agrochemicals for designing novel pesticides with improved efficacy.
