Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of neuroactive drugs and enzyme inhibitors. Its spirocyclic structure with sulfur and nitrogen heteroatoms enhances binding selectivity in receptor-targeted therapies. Commonly employed in medicinal chemistry for optimizing pharmacokinetic properties such as solubility and metabolic stability. Also explored in the design of novel antimicrobial and central nervous system agents due to its rigid scaffold and polarity.
