Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, and dyes. It participates in esterification and alkylation reactions, enabling the introduction of ester or acetate groups into molecules. Commonly employed in the preparation of beta-keto esters and other carbonyl-containing compounds through Claisen condensation. Also utilized in the synthesis of plant growth regulators and certain herbicides. Due to its reactivity, it is valuable in creating complex organic structures in research and industrial settings. Handle with care as it is corrosive and toxic.
