Used as an intermediate in the synthesis of pharmaceuticals and biologically active compounds. Its structure supports the development of nitrogen-containing heterocycles, which are common in drug molecules. Commonly applied in research settings for the preparation of fluorescent dyes and agrochemicals due to its reactivity and functional group compatibility. Also serves as a building block in the development of certain proteolysis-targeting chimeras (PROTACs) and other targeted therapies in medicinal chemistry.
