Used as a key intermediate in the synthesis of mefenamic acid, a nonsteroidal anti-inflammatory drug (NSAID) commonly prescribed for pain relief, particularly in conditions like arthritis and menstrual pain. Its structure allows for efficient conversion into the final active pharmaceutical ingredient through amidation and hydrolysis steps. Widely utilized in pharmaceutical research and development for optimizing production routes of fenamate-class NSAIDs. Also serves in studies involving organic synthesis methodologies, especially in exploring sulfonamide-based transformations and ester modifications.
