Used in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a key intermediate in the production of pyridine derivatives, dyes, and UV absorbers. Commonly employed in the acetoacetic ester synthesis to form ketones, it enables the alkylation of active methylene groups. Also utilized in the manufacture of flavor and fragrance compounds due to its fruity odor. Plays a role in the synthesis of heterocyclic compounds and beta-keto esters for fine chemical applications.
