Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of sulfonamide-based pharmaceuticals. It serves in creating inhibitors for enzymes such as carbonic anhydrase due to the presence of the sulfonamide group, which is known for its affinity to zinc in enzyme active sites. Its carboxylic acid functionality allows for further chemical modifications, making it valuable in medicinal chemistry for designing drug candidates with improved solubility and binding properties. Also utilized in research settings to develop novel anti-inflammatory or anticancer agents.
