Used as a key intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the production of selective COX-2 inhibitors. Its structure allows for efficient functional group transformations, making it valuable in building complex pharmaceutical molecules. Commonly employed in medicinal chemistry for constructing benzene-ring-based active pharmaceutical ingredients (APIs) with enhanced metabolic stability and targeted biological activity. Also utilized in research settings for developing novel analgesic and antipyretic compounds.
