Used in pharmaceutical research as a chiral intermediate for synthesizing biologically active compounds. Shows potential in the development of enzyme inhibitors due to its structural similarity to known protease inhibitors. The thiadiazole ring enhances binding affinity to certain protein targets, making it valuable in medicinal chemistry for designing novel therapeutics. Also employed in asymmetric synthesis where the stereochemistry plays a critical role in biological activity. Its hydrochloride salt form improves solubility and stability, facilitating use in biological assays.
