Used primarily as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the preparation of benzophenone-based pharmaceuticals. Its structure allows for efficient conjugation in photochemical and thermal reactions, making it valuable in developing photostabilizers and UV-absorbing compounds. Also employed in research for designing enzyme inhibitors due to its ability to mimic peptide bonds and participate in hydrogen bonding. Its α,β-unsaturated carbonyl system enables Michael addition reactions, useful in medicinal chemistry for building complex molecules.
