Used as an intermediate in organic synthesis, particularly in the production of dyes, pharmaceuticals, and agrochemicals. Its cyano and ester functional groups allow for versatile reactivity, enabling condensation reactions to form cyanoacrylates or other fine chemicals. Commonly employed in Knoevenagel condensations to build unsaturated nitrile compounds. Also finds use in the synthesis of UV absorbers and specialty polymers due to its ability to introduce both polar and reactive sites into molecular structures.
