Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors for antiviral drugs against chronic infections such as hepatitis C virus (HCV) and HIV. Its structure supports the formation of complex molecules with biological activity, making it valuable in medicinal chemistry for drug discovery. The presence of functional groups like sulfamoyl and thiol allows for selective modifications, enabling optimization of pharmacokinetic properties in candidate drugs. Commonly applied in research settings for designing inhibitors targeting specific enzymes involved in disease pathways.
