Used as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves as a building block in the preparation of sulfonamide-based drugs, which exhibit a range of biological activities including antimicrobial, antiviral, and anti-inflammatory properties. Its structure allows for selective modifications, making it valuable in medicinal chemistry for designing enzyme inhibitors and receptor ligands. Also employed in research settings for synthesizing novel bioactive molecules and in the optimization of drug candidates through structure-activity relationship studies.
