Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of anticoagulant and anti-inflammatory drugs. Its structure, featuring tert-butylsulfonyl and benzyl groups, allows for selective modification to enhance bioavailability and target specificity while providing stability and controlled reactivity. Commonly employed in research settings to design enzyme inhibitors, especially those targeting serine proteases involved in blood coagulation pathways. Also utilized in the preparation of chiral building blocks for complex organic molecules in medicinal chemistry.
