Used in the synthesis of barbiturates, a class of drugs with sedative and hypnotic effects. Commonly employed in the preparation of substituted malonates for pharmaceuticals and agrochemicals. Serves as a building block in organic synthesis, especially in the malonic ester synthesis to form carboxylic acids. Applied in the production of flavor and fragrance compounds due to its ability to form esters with pleasant odors. Utilized in the manufacture of dyes and pigments as an intermediate in condensation reactions. Acts as a precursor in the synthesis of vitamins, particularly vitamin B1 and vitamin B6. Used in polymer chemistry to modify resins and improve flexibility and solubility.
