Used primarily as an intermediate in organic synthesis, particularly in the production of fragrances and flavoring agents. Its ester structure makes it valuable in constructing complex molecules through condensation and alkylation reactions. Commonly employed in the preparation of substituted malonic esters, which serve as building blocks for pharmaceuticals and fine chemicals. Also utilized in the synthesis of certain anesthetics and barbiturate-like compounds due to its ability to form cyclic derivatives under specific reaction conditions. Its liquid form and stability facilitate handling in industrial-scale processes.
