Description

Dextran Polyaldehyde MW 40,000

Dextran Polyaldehyde MW 40,000 is a high-purity, polysaccharide aldehyde produced through modification of Dextran to introduce reactive aldehyde functional groups along the polymer backbone. With an average molecular weight of approximately 40,000 Da, it offers a balanced combination of solubility, reactivity, and processability, making it well suited for pharmaceutical research, biomaterials development, and advanced bioconjugation applications.
Dextran Polyaldehyde MW 40,000 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 under mild aqueous conditions, enabling efficient covalent attachment of biomolecules without harsh reagents.
In pharmaceutical, biomedical, and research applications, Dextran Polyaldehyde MW 40,000 is used in:
• Covalent conjugation of proteins, peptides, and small-molecule drugs
• Formation of hydrogels and crosslinked polymer matrices with controlled gel strength
• Drug delivery systems requiring predictable crosslink density and release behavior
• Enzyme immobilization and biosensor development
• Surface modification of nanoparticles and biomaterials
• Research involving aldehyde-mediated bioconjugation chemistry
The moderate molecular weight of Dextran Polyaldehyde MW 40,000 allows for efficient handling and reproducible reaction kinetics while maintaining the inherent biocompatibility of Dextran. This balance supports precise control over network formation and functional performance in advanced biomedical systems.
