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