Description

Dextran Polyaldehyde MW 500,000

Dextran Polyaldehyde MW 500,000 is a high-purity, oxidized polysaccharide produced through controlled oxidation of Dextran to introduce aldehyde functional groups along a very high–molecular weight polymer backbone. With an average molecular weight of approximately 500,000 Da, it is specifically suited for applications requiring maximum crosslinking density, enhanced mechanical strength, and long-term structural stability.
Dextran Polyaldehyde MW 500,000 appears as a white to off-white hygroscopic powder that is freely soluble in water, forming clear to slightly opalescent solutions. The aldehyde groups readily react with primary amines to form Schiff base linkages, enabling efficient covalent bonding under mild, aqueous conditions without the need for harsh reagents.
In pharmaceutical, biomedical, and research applications, Dextran Polyaldehyde MW 500,000 is used in:
• Formation of ultra-high-strength hydrogels and crosslinked polymer networks
• Tissue engineering scaffolds requiring long-term mechanical integrity
• Covalent conjugation of proteins, peptides, and biologics
• Drug delivery systems designed for prolonged retention and sustained release
• Surface modification and coating of medical devices and biomaterials
• Research involving aldehyde-mediated bioconjugation and polymer architecture
The very high molecular weight of Dextran Polyaldehyde MW 500,000 allows for extensive network formation and superior gel strength compared to lower molecular weight grades. It retains the inherent biocompatibility of Dextran while enabling advanced structural and functional design in biomedical systems.
CarboMer supplies Dextran Polyaldehyde MW 500,000 with control over molecular weight distribution, aldehyde content, degree of oxidation, purity, and microbial quality. The material is suitable for regulated pharmaceutical research, biomedical development, and advanced material science applications.
The material is packaged in sealed, moisture-resistant, tamper-evident containers. Available in laboratory and pilot-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and complete traceability.
Each batch is tested for identity (IR), molecular weight profile, aldehyde content, loss on drying, and microbial limits. Technical support is available to assist with conjugation strategies, formulation design, and application-specific requirements.
As with all CarboMer supplied polysaccharide derivatives, Dextran Polyaldehyde MW 500,000 is supported by rigorous quality control, and expert technical guidance to ensure consistent and reliable performance in pharmaceutical and biomedical research.
