Dextran

Dextran (CAS 9004-54-0) is a branched polysaccharide produced by bacterial fermentation, available in molecular weight-defined grades including Dextran 40 and Dextran 45. It functions as a plasma volume expander and chromatography matrix.

This versatile compound serves as a rheology modifier across pharmaceutical, biotech, and food applications. In pharmaceutical manufacturing, specific molecular weight fractions are used as intravenous plasma expanders and carriers in drug delivery formulations.

Biotech and life science laboratories rely on this material as a size-exclusion chromatography standard. It also serves as a scaffold for conjugating proteins, antibodies, and diagnostic reagents for various analytical procedures.

Food-grade material is used in bakery applications to improve dough rheology, crumb structure, and moisture retention during shelf life. In cosmetic and topical formulations, it acts as a humectant and film-forming agent.

The product is supplied as a white to off-white powder in a broad range of molecular weight fractions. These range from low-MW grades around 10,000 Da up to several million Da to suit specific industrial needs.

Pharmaceutical-grade material is available to USP and Ph. Eur. specifications for clinical use. Research-grade fractions are offered with narrow molecular weight distributions for analytical and biotech use.

Food-grade supply is also commercially available for functional ingredient applications. Our inventory ensures consistent quality and purity across all molecular weight distributions for your specific manufacturing requirements.
