Carboxymethyl Chitosan (CAS 83512-85-0) represents a significant advancement in the functionalization of chitosan, a natural biopolymer derived from chitin. The introduction of carboxymethyl groups (-CH2COOH) onto the chitosan backbone fundamentally alters its properties, most notably enhancing its water solubility and introducing reactive carboxylic acid functionalities. This transformation unlocks a vast array of applications across various industrial sectors, from pharmaceuticals and cosmetics to food and textiles. For professionals looking to integrate this versatile material, understanding its chemistry and sourcing it from a reputable manufacturer is paramount.

The synthesis of Carboxymethyl Chitosan typically involves the reaction of chitosan with a carboxymethylating agent, such as sodium chloroacetate, under alkaline conditions. Key parameters like reaction time, temperature, pH, and the molar ratio of reactants directly influence the degree of substitution (DS) and the molecular weight of the final product. Achieving a specific DS, often above 80%, is critical for many applications, as it dictates the material's solubility, viscosity, and chelating ability. When you are ready to buy Carboxymethyl Chitosan, verifying these specifications with your supplier ensures you receive a product tailored to your needs.

The enhanced water solubility of Carboxymethyl Chitosan, particularly at neutral to alkaline pH levels, is a major advantage over native chitosan, which is only soluble in acidic solutions. This improved solubility simplifies processing and formulation, making it easier to incorporate into aqueous systems. Furthermore, the presence of the carboxylic acid groups provides sites for ion exchange, metal chelation, and further chemical modifications, opening avenues for developing advanced materials with tailored functionalities. For instance, its ability to chelate metal ions makes it useful in water treatment and as a carrier for metal-based therapeutic agents.
