Abstract
A novel conjugate of a support material and an oligomer or polymer of a saccharide that is linked to the support material via urea linkages, and in which the oligomers or polymers are cross-linked via urea linkages provides a valuable stationary phase for chromatography. It is particularly valuable as a chiral stationary phase in enantiomeric separations and enantiomeric analysis.
Claims24
A conjugate comprising a support material linked to oligomers or polymers of a saccharide, which linking is via urea linkages between the saccharide moieties and the support material, and wherein the oligomers or polymers are also cross-linked via urea linkages.
