  • Separating agent for enantiomeric isomers
    Publication number: 20090008329
    Abstract: Provided is a separating agent for enantiomeric isomers that is advantageous from the production standpoints of having a high enantiomeric resolution ability inherent in polysaccharide derivatives, solvent resistance, high solubility in a reaction solvent, and good filtration property. That is, the separating agent for enantiomeric isomers includes a polysaccharide oligomer derivative derived from a polysaccharide oligomer having a number-average degree of polymerization of from 5 to less than 50, supported on a carrier.
    Type: Application
