Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a key building block for thienyl-substituted compounds that exhibit anti-inflammatory and analgesic properties. Its structure allows for effective conjugation in multi-step organic reactions, making it valuable in medicinal chemistry for designing drug candidates with improved selectivity and metabolic stability. Also utilized in research settings for developing novel heterocyclic compounds with potential biological activity.
