Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. It plays an important role in the synthesis of barbiturates and other central nervous system depressants. Its active methylene group allows for easy alkylation, making it valuable in constructing complex carbon skeletons. Also utilized in the production of heterocyclic compounds and as a building block in the development of dyes, fragrances, and agrochemicals. Its ester groups enable further functional transformations, supporting its versatility in multi-step synthetic routes.
