Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceutical compounds. It serves as a building block in the development of bioactive molecules due to its stability and reactivity in various coupling reactions. Commonly employed in the synthesis of sulfonamide-based drugs, which exhibit antimicrobial, antiviral, and enzyme inhibitory properties. Its structure allows for easy modification, making it valuable in medicinal chemistry for structure-activity relationship studies. Also utilized in the development of protease inhibitors and receptor antagonists in drug discovery programs.
