Carboxymethyl Chitosan is a water-soluble chitosan derivative that Sarchem Labs supplies as a white-to-light-yellow/light-brown powder for biomedical materials research, drug delivery, and tissue-engineering applications. Chemical modification of chitosan’s backbone with carboxymethyl groups improves its water solubility relative to unmodified chitosan while retaining the biocompatibility that makes chitosan derivatives attractive for biomedical use. Every lot ships with a Certificate of Analysis and Safety Data Sheet.

Product Description

What is Carboxymethyl Chitosan?

Carboxymethyl Chitosan is produced by chemically modifying chitosan — itself derived from chitin — with carboxymethyl groups along its polysaccharide backbone. That modification increases water solubility (which depends on the degree of carboxymethylation) while preserving chitosan’s inherent biocompatibility, mucoadhesion, and gel-forming characteristics.

Uses of Carboxymethyl Chitosan

Carboxymethyl chitosan’s biocompatibility and tunable solubility make it a widely studied material in drug-delivery and tissue-engineering research, where it’s evaluated for manufacturing films, tablets, and nanotechnology-based delivery systems suitable for scale-up. Its ability to interact with cells also supports research into cell growth, tissue regeneration, and wound-healing applications.

FAQs: Carboxymethyl Chitosan

Mainly in drug-delivery and tissue-engineering research, including film, tablet, and nanoparticle formulation development, and in wound-healing and cell-growth studies.

The carboxymethyl groups introduced onto the chitosan backbone increase its water solubility, with the degree of solubility improvement depending on how much of the backbone has been carboxymethylated (Sarchem's material is ≥80% carboxymethylated).

No — like other biopolymers, it doesn't have a single fixed molecular formula or weight; it's characterized instead by its degree of carboxymethylation and physical form.
