Used as a key intermediate in the synthesis of thienothiazine-based pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 inhibitors. Its structure supports high binding affinity to cyclooxygenase enzymes, making it valuable in creating potent anti-inflammatory and analgesic agents. The compound’s functional groups allow for further chemical modifications, enabling optimization of pharmacokinetic properties such as solubility, metabolic stability, and bioavailability in drug design.
