HEPPE MEDICAL CHITOSAN GMBH Chitosan

CAS Number
9012-76-4
EC Number
618-480-0
Chemical Name
Chitosan
Molecular Formula
(C₆H₁₁NO₄)ₙ

Chitosan is a nitrogenous polysaccharide. The monomer of chitosan is glucosamine. Chitosans in dissolved form are positively charged. Due to their different degrees of deacetylation and molecular weights, chitosans are a large group of substances with different properties.

Derivatives

Chitin and chitosan derivatives are extremely versatile. Most of them are directly soluble in water and, depending on their derivatisation, can be applied in neutral and basic pH ranges. Thus, the derivatives have very comprehensive and customized potential applications. Our standard derivatives include:; Chitosan HCl; N, O-Carboxymethyl-Chitosan (CMC); Chitosan Lactate; Chitosan Acetate; Chitosan Glutamate

Chitosan Oligomer

Chitosan oligosaccharide is an oligomer of β-(1 ➔ 4)-linked d-glucosamine. Chitosan oligomer can be prepared from the deacetylation and hydrolysis of chitin.

Production Process

Chitosan differs from chitin in that it has free amino groups (figure 1) and is obtained by deacetylizing chitin. At a minimum deacetylization level of 70% (=amount of free amino groups in the polymer) it is considered to be chitosan. The monomer of chitosan is D-amino glucose.

Manufacturing Process

In the deacetylation process, chitin is subjected to treatment with concentrated lye to dissociate acetyl groups from the polymer. The result is chitosan that, depending on the degrees of deacetylation and polymerization (chain length), has more or less pronounced properties.
