Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the formation of biologically active compounds that target specific signaling pathways in tumor cells. Also employed in research settings to design anti-inflammatory and antiviral drugs due to its favorable binding properties with enzyme active sites. The sulfone and carboxylic acid functional groups enhance solubility and stability, making it suitable for formulation in drug discovery programs.
