Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in medicinal chemistry due to its ability to form stable derivatives that can enhance drug bioavailability and target specificity. Also employed in the preparation of kinase inhibitors and other biologically active compounds in research settings. Its sulfonamide group facilitates interactions with enzymes and proteins, making it valuable in designing enzyme inhibitors.
