Used primarily in organic synthesis, especially in the preparation of biologically active compounds. It serves as a key intermediate in pharmaceutical research, where it reacts with amines to form thiourea derivatives, which are important in drug development for their enzyme inhibitory properties. Commonly applied in the synthesis of agrochemicals and fluorescent probes due to its ability to modify biomolecules for detection and imaging. Also utilized in the development of sensors and functional materials where selective binding and signal transduction are required.
