Manufacturing Quality Control of Isomannide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 205 nm, comparing peak area to a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in anhydrous methanol-based solvent. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organics, then weighing inorganic residue as percentage of original mass. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities in plasma. |
| Chloride | Potentiometric Titration | Titration with silver nitrate using silver/silver chloride electrode to detect endpoint via potential change. |
| Sulfate | Barium Sulfate Gravimetry | Precipitation as BaSO4 in acidic medium followed by filtration, drying, and weighing of precipitate. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV against reference standards or threshold limits. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through solution, indicating enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, reflecting crystallinity and purity. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in saturated aqueous solution using calibrated glass electrode. |
| Appearance | Visual Inspection | Assessment of color and clarity against water-white standard under controlled lighting and viewing conditions. |
| Solubility | Qualitative Solubility Test | Observation of complete dissolution in specified solvents (e.g., water, ethanol) at defined temperature and concentration. |
