Description

Dextran Polyaldehyde MW 250,000

Dextran Polyaldehyde MW 250,000 is a high-purity, oxidized polysaccharide produced through controlled modification of Dextran to introduce aldehyde functional groups along the polymer backbone. With an average molecular weight of approximately 250,000 Da, it is designed for applications requiring high molecular weight polymers with enhanced crosslinking capacity, mechanical strength, and structural stability.
Dextran Polyaldehyde MW 250,000 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.
In pharmaceutical, biomedical, and research applications, Dextran Polyaldehyde MW 250,000 is used in:
• Formation of high-strength hydrogels and polymer networks
• Tissue engineering scaffolds and regenerative medicine platforms
• Covalent conjugation of proteins, peptides, and biologics
• Drug delivery systems requiring prolonged residence time and mechanical integrity
• Surface modification of biomaterials and medical devices
• Research involving aldehyde-mediated bioconjugation and polymer chemistry
The high molecular weight of Dextran Polyaldehyde MW 250,000 enables increased crosslink density and improved mechanical performance compared to lower molecular weight grades. It maintains the biocompatibility of Dextran while providing enhanced functional versatility for advanced biomedical systems.
