Used primarily in organic synthesis, especially in the preparation of barbiturates, which are central nervous system depressants with sedative and hypnotic effects. Serves as a key building block in the Knoevenagel condensation reaction to form α,β-unsaturated carbonyl compounds. Employed in the synthesis of various pharmaceuticals, dyes, and agrochemicals due to its active methylene group that readily undergoes alkylation. Also utilized in fragrance and flavor industries for creating ester-based aroma compounds. Acts as a precursor in the production of vitamins, such as vitamin B1 and B6. Its ability to form cyclic structures makes it valuable in the manufacture of polymers and specialty chemicals.
