Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Acts as a building block in the preparation of fragrances and flavoring agents due to its aromatic character. Employed in research for cinnamic acid derivatives, which show potential biological activities including antimicrobial and antioxidant properties. Also utilized in the development of photoresponsive materials because of its ability to undergo [2+2] cycloaddition upon UV irradiation, useful in smart polymers and molecular switches.
