Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and dyes. It serves as a building block in the development of pharmaceuticals, including anti-inflammatory and antimicrobial agents. Its structure allows for easy functionalization, making it valuable in the design of sulfonamide-based drugs. Also employed in the synthesis of fluorescent probes and sensors due to its favorable photophysical properties. Commonly utilized in research settings for the development of new bioactive molecules and in medicinal chemistry for structure-activity relationship studies.
