Manufacturing Quality Control of METHYL-ALPHA-D-MANNOPYRANOSIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by separation and flame ionization detection relative to calibrated standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Identifies and quantifies impurities based on retention time and response relative to main peak. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines water via electrochemical reaction between iodine and water in anhydrous methanol/pyridine medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals (e.g., Pb, Cd, Hg, As) by atomic absorption of characteristic wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions by titration with silver nitrate using silver electrode endpoint detection. |
| Sulfate Content | Gravimetric Analysis as BaSO4 | Precipitates sulfate as barium sulfate and determines mass after filtration and drying. |
| Acid Value | Acid-Base Titration with NaOH | Neutralizes free acidic groups using standardized sodium hydroxide and phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral molecules in solution at specified concentration and path length. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| Solubility | Qualitative Solubility Test | Evaluates dissolution behavior in specified solvents (e.g., ethanol, chloroform, water) at defined temperature. |
