Description

General description

The chiral resolution of DL-malic acid by ligand-exchange capillary electrophoresis was studied.

Application

DL-Malic acid (MA) can be used:

• As a dopant in the ammonium dihydrogen phosphate (ADP) crystal to improve the properties of ADP crystals.
• To form a water-soluble complex, Nb-MA which can further react with LiCl to form lithium niobate (LiNbO₃) powders.
• As a monomer to synthesize a co-polymer, poly(DL-lactic acid-co-α,β-malic acid) (PLMA) with DL-lactic acid which can be coated over magnetic Fe₃O₄ nanoparticles after functionalizing with fluorescein isothiocyanate (FITC), to be used as a MRI T2-contrast agent.
