D-(+)-Malic Acid (CAS: 636-61-3) used as an acidulant and flavoring agent, food additive. And it is also used in the place of the less sour citric acid in sour sweets.
D-(+)-Malic Acid (CAS: 636-61-3) is an important four-carbon atoms chiral pool. It is mainly used in many fields including chiral pharmaceuticals, chiral additives and chiral auxiliaries. It is used as chiral pool of chiral synthesis in pharmaceutical and food industries. As an optically active organic acid, it is insubstitutable in asymmetry synthesis of some chiral compounds.
The naturally occuring isomer is the L-form which has been found in apples and many other fruits and plants. Selective α-amino protecting reagent for amino acid derivatives. Versatile synthon for the preparation of chiral compounds including κ-opioid receptor agonists, 1α,25-dihydroxyvitamin D3 analogue, and phoslactomycin B.
