Description

Dextran Polyaldehyde MW 150,000

Dextran Polyaldehyde MW 150,000 is a high-purity, chemically modified polysaccharide produced by controlled oxidation of Dextran to introduce reactive aldehyde functional groups along the polymer backbone. With an average molecular weight of approximately 150,000 Da, it is widely used in pharmaceutical research, biomaterials development, and advanced drug delivery systems that require high molecular weight polymers capable of extensive crosslinking and structural reinforcement.
Dextran Polyaldehyde MW 150,000 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 amine groups to form Schiff base linkages, enabling covalent bonding under mild, aqueous conditions.
In pharmaceutical, biomedical, and research applications, Dextran Polyaldehyde MW 150,000 is used in:
• Formation of high-strength hydrogels and crosslinked polymer networks
• Tissue engineering scaffolds and regenerative medicine platforms
• Covalent conjugation of proteins, peptides, and biologics
• Drug delivery systems requiring prolonged residence time or structural stability
• Surface modification of medical devices and biomaterials
• Research involving aldehyde-mediated bioconjugation and polymer chemistry
The higher molecular weight of Dextran Polyaldehyde MW 150,000 allows for increased crosslink density and mechanical strength in gel systems compared to lower molecular weight analogs. It retains the biocompatibility of Dextran while offering enhanced structural integrity and functional versatility.
CarboMer supplies Dextran Polyaldehyde MW 150,000 with control over molecular weight distribution, aldehyde content, degree of oxidation, purity, and microbial quality. The material is suitable for regulated pharmaceutical research and advanced biomedical 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.
