Industrial Applications of Dextran Sulfate Sodium Salt
| Industry | Applications | Processing |
|---|---|---|
| Pharmaceuticals | Anticoagulant; treatment of hyperlipidemia and atherosclerosis; inducer of intestinal mucosal barrier injury in experimental models (e.g., DSS-induced colitis) | Administered via intravenous injection or oral dosing; dissolved in drinking water or administered by gavage in animal studies |
| Biotechnology | Cell culture supplement to promote cell adhesion and proliferation; enhancer of viral/gene transfection (improves nucleic acid uptake efficiency) | Added to culture medium at 0.1–1% (w/v); co-incubated with nucleic acid–transfection reagent complexes prior to addition to cells |
| Pharmaceutical Manufacturing | Excipient in sustained-release formulations (increases viscosity and modulates release rate); stabilizer or coating material in microsphere/nanoparticle preparation | Sustained-release microspheres/nanoparticles prepared via wet granulation, spray drying, or emulsion–solvent evaporation |
| Food | Dietary fiber supplement (approved as a functional food ingredient in certain jurisdictions) | Incorporated into beverage and meal-replacement powder matrices at concentrations typically ≤5% (w/v) |
Manufacturing Quality Control of Dextran Sulfate Sodium Salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Dextran Sulfate Sodium Content) | Acid-Base Titration | Quantifies sulfate ester groups via back-titration after acid hydrolysis and barium chloride precipitation. |
| Sodium Content | Flame Photometry | Measures sodium ion emission intensity at characteristic wavelength in flame excitation. |
| Sulfate Content | Gravimetric Analysis (Barium Sulfate) | Precipitates sulfate as BaSO4 and determines content from dried precipitate mass. |
| Molecular Weight Distribution | Size Exclusion Chromatography (SEC) | Separates polymer chains by hydrodynamic volume using calibrated columns and refractive index detection. |
| Residual Solvents (e.g., Ethanol, Acetone) | Gas Chromatography (GC-FID) | Separates and quantifies volatile solvents based on retention time and flame ionization response. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Ionizes sample and detects elemental isotopes with high sensitivity and multi-element capability. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) | Measures mass loss upon controlled heating to determine volatile and moisture content. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in standardized solution. |
| Clarity and Color | Visual Inspection and Hazen Color Scale | Assesses solution appearance against standard platinum-cobalt color solutions and visual clarity criteria. |
| Microbial Contamination | Membrane Filtration and Plate Count | Filters sample, incubates on nutrient media, and enumerates viable aerobic bacteria and fungi. |
| Protein Impurity | Lowry Assay | Quantifies protein via copper-protein complex formation followed by Folin-Ciocalteu reagent color development. |
| Residual Catalyst (e.g., NaNO2) | Spectrophotometry (UV-Vis) | Detects nitrite by diazotization reaction forming a colored azo dye measured at specific wavelength. |
