Description

Dextran Polyaldehyde MW 70,000

Dextran Polyaldehyde MW 70,000 is a high-purity, oxidized polysaccharide produced by controlled oxidation of Dextran to introduce reactive aldehyde functional groups along the polymer backbone. With an average molecular weight of approximately 70,000 Da, it offers a balance of reactivity, solubility, and mechanical contribution, making it well suited for pharmaceutical research, biomaterials development, and advanced drug delivery applications.
Dextran Polyaldehyde MW 70,000 appears as a white to off-white hygroscopic powder that is freely soluble in water, forming clear to slightly opalescent solutions. The aldehyde functionalities readily react with primary amines to form Schiff base linkages, enabling efficient covalent conjugation under mild, aqueous conditions.
In pharmaceutical, biomedical, and research applications, Dextran Polyaldehyde MW 70,000 is used in:
• Covalent conjugation of proteins, peptides, and small-molecule drugs
• Formation of hydrogels and crosslinked polymer networks with moderate gel strength
• Drug delivery systems requiring controlled crosslink density and release profiles
• Enzyme immobilization and biosensor development
• Surface modification of biomaterials and nanoparticles
• Research involving aldehyde-mediated bioconjugation chemistry
The intermediate molecular weight of Dextran Polyaldehyde MW 70,000 allows for predictable crosslinking behavior and manageable viscosity, supporting reproducible formulation and processing. It retains the biocompatibility of Dextran while providing enhanced functional versatility for biomedical and pharmaceutical systems.
