Manufacturing Quality Control of BETA-D-GLUCOSAMINE PENTAACETATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Glucosamine Tetraacetate Content) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Related Substances | HPLC with UV detection | Separation and detection of structurally similar impurities (e.g., mono-, di-, tri-acetylated glucosamine) using gradient elution. |
| Water Content | Karl Fischer titration | Electrochemical titration measuring water via reaction with iodine, sulfur dioxide, and base in methanol/pyridine medium. |
| Residue on Ignition | Gravimetric analysis (weight loss on ignition) | Mass difference before and after heating at 700-800 C to determine inorganic ash content. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification by ionization in plasma and mass-selective detection at trace levels. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride anions after suppressed eluent chromatography. |
| Sulfate Impurity | Ion Chromatography (IC) | Separation and conductivity detection of sulfate anions using carbonate/bicarbonate eluent. |
| pH of Aqueous Solution | Potentiometric pH measurement | Measurement of hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral D-glucosamine tetraacetate in solution. |
| Loss on Drying | Thermogravimetric analysis (TGA) or oven drying | Mass loss measured after drying at 105 C for 2 hours under atmospheric pressure. |
| Microbial Contamination | Membrane filtration followed by TSA/TSA+CA plate count | Viable aerobic microorganisms captured on membrane filter and enumerated on tryptic soy agar (TSA) and TSA with cycloheximide (TSA+CA). |
| Residual Solvents (Acetic Anhydride, Acetic Acid) | Gas Chromatography (GC) with FID | Separation and flame ionization detection of volatile organic solvents using capillary column and headspace sampling. |
