What's CAS 9004-54-0 Dextran 40 Powder

Product Name	Dextran 40
CAS	9004-54-0
Molecular Formula	（c6h10o5）n
Molecular Weight	178.27
Appearance	White powder

Dextran products have different molecular weights, and the quality control requires that the molecular weight will vary

depending on the molecular weight of the product. Other quality control requirements are the same

Dextran-40, also known as low molecular dextran, can increase plasma colloidal osmotic pressure, increase blood volume,

reduce platelet adhesion and inhibit red blood cell aggregation, reduce blood viscosity, reduce peripheral circulatory

resistance, and dredge microcirculation. It can increase the effective kidney filtration pressure and glomerular filtration

rate, and exert osmotic diuretic effect in the renal tubules.

 

Medicine for blood volume expansion, improved plasma colloid osmotic pressure, increase of plasma volume and

maintain blood pressure, prevent shock, can prevent the red blood cell and platelet aggregation, reduce blood viscosity,

which has the effect of improving microcirculation.
