제목 NMR spectroscopic characterization of N,O and N-O Carboxymethyl Chitosan
초록 Carboxymethyl chitosan(CMCh) was prepared by chemical reaction with mono-chloroacetic acid and glyoxylic acid to low molecular weight water soluble chitosan(LMWSC) of C6-OH (O-Carboxymethyl chitosan), C2-NH2 (N-Carboxymethylc chitosan) and both C6-OH and C2-NH2 (N,O-Carboxymethyl chitosan) group to apply as an ionic-drug carrier. The structure were characterized by 1H-NMR, 13C-NMR, DEPT 135 and HMQC (Heteronuclear Multiple Quantum Correlation). Degree of substitution (DS) and degree of deacetylation(DDA) of CMCh was determined by 1H-NMR.
