Malonic Acid (Cat No.:R018716) is a dicarboxylic acid widely used as a versatile building block in organic synthesis. Its active methylene group, flanked by two carboxylic acids, makes it highly reactive in Knoevenagel condensations, decarboxylations, and nucleophilic substitutions. Malonic acid is instrumental in the preparation of barbiturates, vitamins (like B1), and flavoring agents. It also serves as a precursor in the synthesis of pharmaceuticals, agrochemicals, and specialty polymers. With good solubility in water and polar solvents, it is a key reagent in both academic and industrial chemistry.
