CARBOXYMETHYL CHITOSAN(MEDICAL GRADE)

 

Product Introduction

 

Carboxymethyl chitosan can also be prepared as the preparation of carboxymethyl chitin by reacting with chloroacetic acid in the presence of base, but carboxymethyl chitin is substituted on c6-OH of sugar residues, and a small amount of carboxymethyl chitosan is substituted on C3-OH to produce O-carboxymethyl chitin. The case of chitosan is more complex -, carboxymethyl will not only in -OH substitution, but also in -NH substitution, the formation of O- carboxymethyl and N- carboxymethyl chitosan, in fact, there are several possible substitution cases :C6-O- carboxymethyl, C2-N_ carboxymethyl, C3-O- carboxymethyl, C6-O, C2-N- carboxymethyl, C6-O, C3-O, C2-N- carboxymethyl, c6-O, C3-O, C2-N- carboxymethyl, etc. Because of the steric hindrance effect on C3 and the intramolecular hydrogen bond between C2 and C3, carboxmethyl on C3 is more difficult to occur, so the substitution of carboxmethyl on the hydroxyl group, C3-O- carboxmethyl is less, and C6-O- carboxmethyl is dominant. For C6 - OH and C2 - NH, carboxymethyl in alkaline conditions to replace activity than on hydroxyl amino, therefore, when the substitution degree is less than 1, carboxymethyl replace is mainly on the hydroxyl amino, rather than only the substitution degree is close to 1 and above 1, will happen at the same time amino carboxymethyl replaced, the formation of O, N - carboxymethyl chitosan. The water solubility of carboxymethyl chitosan, in addition to it is a carboxymethyl sodium salt dissolved in water, there is another reason is the introduction of carboxymethyl chitosan, destroyed the secondary structure of chitosan molecules, so that its crystallinity is greatly reduced, almost become amorphous.

 

Carboxymethyl chitosan is a kind of advanced derivative of natural marine biological chitosan.It is a kind of amphoterous polyelectrolyte with good water solubility,film information,moisture and water retention,antibacterial and strong chelation.At the same time,it has biocompatibility,biodegradability,hemostasis and cullus function.It has no cytotoxicity and biological safety,and can be used for medical dressing.It has important applications in medicine,health care products,cosmetics,fresh preservation,environmental protection,chemical industry and other fields.Its stable properties,antibacterial and anti-infection,lipid-lowring and arteriosclerosis prevention and other pharmacological effects are destined to play a greater role in the future of human life.
