Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for designing drug candidates. It is also employed in agrochemical research for creating novel pesticides and herbicides due to its ability to enhance binding selectivity in target molecules. Additionally, it serves as a building block in the preparation of dyes and functional materials where nitrogen-containing heterocycles are required.
