Manufacturing Quality Control of (2R,3R,4S,5R)-2,3,4,5,6-pentahydroxyhexanoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies carboxylic acid groups by neutralization with standardized sodium hydroxide solution. |
| Moisture Content | Karl Fischer Titration | Measures water content via iodine-sulfur dioxide redox reaction in a methanol-based reagent. |
| Specific Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring rotation of plane-polarized light in solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal impurities by atomic absorption of characteristic wavelengths in flame or graphite furnace. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using a silver indicator electrode. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally similar impurities using reversed-phase chromatography and UV absorbance. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines acidity/basicity of a defined aqueous solution using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Identifies purity and identity by observing temperature range at which solid transitions to liquid. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures volatile content loss under controlled heating and atmospheric conditions. |
| Iron Content | ICP-OES | Quantifies iron and other metals simultaneously via emission intensity of excited atoms in plasma. |
