What is Dextran CAS 9004-54-0?

Chemical name

Molecular formula: (C 6 H 10 O 5) n

The degree of polymerization n determines the molecular weight.

CAS Number: 9004-54-0

EINECS number: 232-677-5

Source and Structure

Natural sources: Mucus secreted by microorganisms (such as Enterostromyces intestinalis), plant cell walls.

Structural characteristics:

α -glucan: The main chain is connected by α-1,6 glycosidic bonds and contains α-1,3/α-1,4 side chains (such as dextran).

β -glucan: The main chain is connected by β-1,3 glycosidic bonds and contains β-1,6 side chains (such as yeast glucan).

Dextran CAS 9004-54-0 Use

1.  Medicine and Clinical Practice

Plasma substitutes: Medium molecular weight Dextran (such as DEXtran 40/70) is used to expand blood volume and prevent shock.

Drug carrier: As a sustained-release material to encapsulate drugs and prolong therapeutic effects (such as the delivery of anti-cancer drugs).

Biological separation: Glucan gels (such as Sephadex®) are used for chromatographic purification of proteins and nucleic acids.

2.  Food industry

Thickening stabilizer: Addition amount 0.1% - 1%, to improve the texture of bread and dairy products.

Functional health care: β -glucan regulates blood sugar and enhances immunity (such as from oats and yeast sources).

3.  Cosmetics and Personal care

Moisturizing and repairing: β -glucan promotes the repair of the skin barrier and is used in essence and face cream (concentration 0.5% - 2%).

Antioxidant: Eliminate free radicals and delay skin aging.

4.  Industry and Scientific Research

Biological protectants: Low-molecular-weight Dextran (such as Dextran 10) is used for cryopreservation of cells/organs.

Industrial additives: Papermaking adhesives, textile lubricants.
