description Product Description
Used as a key intermediate in the synthesis of pharmaceuticals, dyes, and agrochemicals. Its active methylene group allows it to undergo condensation reactions, making it valuable in producing heterocyclic compounds like pyrazoles and pyrimidines. Commonly employed in the preparation of vitamins, particularly vitamin B1 and vitamin B6. Also utilized in the manufacture of pigments and functional polymers due to its ability to introduce ester and ketone functionalities in organic synthesis. Frequently applied in the Knoevenagel condensation for creating unsaturated compounds used in fragrances and specialty chemicals.
