Used as an intermediate in organic synthesis, particularly in the development of dyes and pigments due to its conjugated structure and ability to undergo further functionalization. Its extended π-system makes it suitable for applications in photoactive compounds and UV-absorbing materials. Also explored in pharmaceutical research for building blocks in nitrogen-containing heterocycles, especially in Schiff base derivatives with potential biological activity. Employed in the preparation of specialty esters and amides through selective reactions at the ester or imine functional groups. Shows utility in material science for designing nonlinear optical materials owing to electron donor-acceptor characteristics.
