Used in organic synthesis as a building block for pharmaceuticals and fine chemicals. Serves as a photoremovable protecting group in light-sensitive compounds due to its ability to undergo trans–cis isomerization upon UV irradiation. Employed in the development of nonlinear optical materials because of its conjugated structure and strong UV absorption. Also investigated for use in sunscreen formulations as a UV absorber, offering protection against skin damage. Its derivative forms are explored in medicinal chemistry for anti-inflammatory and antimicrobial applications.
