Used in the synthesis of pharmaceutical intermediates, particularly in the development of anti-inflammatory and analgesic drugs. Its α,β-unsaturated carbonyl structure makes it a valuable Michael acceptor in organic reactions, enabling the formation of carbon-carbon bonds. Commonly employed in the preparation of cinnamic acid derivatives, which exhibit biological activity such as antioxidant and antimicrobial properties. Also utilized in the design of UV-absorbing compounds for use in sunscreens and polymer stabilizers due to its conjugated system that absorbs in the ultraviolet region.
