The efficacy and versatility of Dextran stem from its unique chemical structure and the precise manufacturing processes employed to produce it. At NINGBO INNO PHARMCHEM CO.,LTD., we leverage advanced technologies to ensure that our Dextran products exhibit the high purity and specific characteristics demanded by the pharmaceutical and biotechnology industries.

Dextran is a complex branched glucan, essentially a polymer of glucose units linked predominantly by α-1,6 glycosidic bonds. This structure allows for varying chain lengths, resulting in different molecular weights, which are critical for its diverse functions. The range of available Dextrans, from low molecular weight variants like Dextran 20 to higher ones like Dextran 70, each possess distinct properties affecting their solubility, viscosity, and biological activity. For example, understanding the dextran 40 bp ep usp specifications is key for its use as a plasma volume expander, where molecular weight significantly influences plasma retention time.

The manufacturing of Dextran typically involves the controlled hydrolysis and subsequent fractionation of polysaccharides produced by specific bacterial strains, such as *Leuconostoc mesenteroides*, from a sucrose substrate. This process requires careful control over reaction conditions, purification steps, and analytical testing to achieve the desired molecular weight distribution and purity. Techniques such as chromatography are employed to isolate fractions with specific average molecular weights, ensuring batch-to-batch consistency.

Our dedication to quality assurance is paramount. We implement rigorous quality control measures throughout the production cycle, from raw material sourcing to the final product. This includes comprehensive testing for appearance, optical rotation, impurity levels (such as chloride, nitrogen, and heavy metals), loss on drying, and residue on ignition. For pharmaceutical applications, testing for bacterial endotoxins and total viable aerobic counts is also critical, ensuring the safety and suitability of our Dextran for injection usp and other parenteral products.
