Manufacturing Quality Control of MAREIN
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies marmin content by separation on a reversed-phase column and UV detection at 320 nm. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally similar impurities using diode-array detection for spectral confirmation. |
| Loss on Drying | Gravimetric Analysis | Measures volatile content by weight loss after drying at 105 C under vacuum. |
| Residue on Ignition | Sulfated Ash Test | Determines inorganic residue after combustion of sample with sulfuric acid and subsequent incineration. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other heavy metals via atomic emission spectroscopy after acid digestion. |
| Chloride Content | Argentometric Titration | Measures chloride ions by titration with silver nitrate using potassium chromate indicator. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as barium sulfate and determines mass after filtration and drying. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric reaction with iodine, sulfur dioxide, and base in methanol. |
| Specific Optical Rotation | Polarimetry | Measures optical activity using sodium D-line light to confirm stereochemical identity and purity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition as an indicator of crystallinity and purity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens per pharmacopeial microbiological testing. |
