Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective COX-2 inhibitors and other anti-inflammatory agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building active drug molecules. It is also employed in the preparation of sulfonamide-based compounds with potential anticancer and antimicrobial activities. Due to the presence of both amino and ester groups, it participates in coupling reactions and heterocycle formation, supporting its role in creating complex bioactive molecules.
