High quality D(+)-Malic Acid,CAS No.:636-61-3
High quality D(+)-Malic Acid CAS No.:636-61-3
D(+)-malic acid: white crystals or white crystalline powder, soluble in water, alcohol and other organic solvent.
It 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.
