Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals and agrochemicals. Its structure allows for selective functionalization, making it valuable in constructing nitrogen-containing heterocyclic compounds. It is also employed in the preparation of fluorescent probes and sensors due to its reactivity and ability to form stable derivatives with amines and other nucleophiles. Additionally, it serves in medicinal chemistry for building blocks in kinase inhibitors and other biologically active molecules.
