METHOD FOR PRODUCING OLIGOSACCHARIDE CHAIN/ PHENYLENEDIAMINE COMPLEX, OLIGOSACCHARIDE CHAIN LINKERED COMPOUND, SULFATED OLIGOSACCHARIDE CHAIN/ PHENYLENEDIAMINE COMPLEX COMPOUND LINKERED BY LINKER COMPOUND

摘要

PROBLEM TO BE SOLVED: To obtain a sulfated oligosaccharide/phenylenediamine complex by using a terminal phenylene diamine group containing polyfunctional amine linkable simply plural oligosaccharide chains controlling the number of the chains.;SOLUTION: This method for producing an oligosaccharide/phenylenediamine complex collected by reacting a reduction end of an oligosaccharide chain of a saccharide having a reduction level at a low pH condition by using a phenylenediamine group-containing polyfunctional amine compound of formula (1) or (2) (n is an integer of 2-7; m is an integer of 1-3; X is OH or H) as a linker compound.;COPYRIGHT: (C)2002,JPO
