Malonic Acid (Propanedioic Acid) (CAS: 141-82-2) acts as a building block in organic synthesis. Malonic Acid is mainly used in pharmaceutical intermediates, specialty chemicals, flavors and fragrances, polymer cross linkers, adhesives, resin additives, electroplating polishing agents, aluminum surface treatment agents, etc. It is also widely used in electronic chemicals and other fields.
Malonic Acid is used as an intermediate in the manufacture of barbiturates and other pharmaceuticals. It is a component used as a stabilizer in many high-end cosmetic and pharmaceutical products. Malonic acid is also used as building block in chemical synthesis, specifically to introduce the molecular group -CH2-COOH. It is used for the introduction of an acetic acid moiety under mild conditions by Knoevenagel condensation and subsequent decarboxylation.
