Used as an intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the production of ibuprofen derivatives. It serves as a key building block in pharmaceutical manufacturing due to its structural similarity to active drug moieties that exhibit analgesic and antipyretic properties. Also employed in the development of novel prodrugs aimed at improving bioavailability and reducing gastrointestinal side effects. Additionally, it finds use in research settings for studying metabolic pathways and enzyme inhibition related to inflammation.
