Used as an intermediate in the synthesis of pharmaceuticals, dyes, and agrochemicals. It participates in the preparation of heterocyclic compounds due to its active methylene group, enabling condensation reactions. Commonly employed in the production of antimalarial drugs and vitamin B1. Also utilized in organic synthesis for constructing complex molecules through Michael addition and Claisen condensation reactions. Its ester functionality allows for further derivatization, making it valuable in fine chemical manufacturing.
