Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Serves as a building block in the preparation of cinnamic acid derivatives, which exhibit biological activities such as antimicrobial, anti-inflammatory, and anticancer properties. Employed in the development of UV-absorbing compounds for use in sunscreens and polymer stabilizers due to its conjugated system that absorbs ultraviolet light. Also utilized in the synthesis of liquid crystals and nonlinear optical materials for electronic and photonic applications.
