Manufacturing Quality Control of PotassiumD-erythronate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Potassium Threonate Content) | Acid-Base Titration with NaOH | Quantifies D-threonic acid moiety by back-titration after hydrolysis and neutralization. |
| Loss on Drying | Gravimetric Analysis (105 C, 2 h) | Measures volatile content including water and residual solvents by weight loss upon heating. |
| Residue on Ignition | Gravimetric Ashing (500-600 C) | Determines inorganic impurities as non-volatile ash after high-temperature combustion. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Sulfated Ash | Gravimetric Ashing with H2SO4 Pretreatment | Measures metallic impurities converted to sulfates prior to ignition and weighing. |
| Chloride | Argentometric Titration (Mohr method) | Determines chloride ions via precipitation titration with AgNO3 using K2CrO4 indicator. |
| Sulfate | Barium Sulfate Gravimetry | Quantifies sulfate as insoluble BaSO4 precipitate formed after addition of BaCl2 solution. |
| pH (1% aqueous solution) | Potentiometric Measurement with pH Meter | Measures hydrogen ion activity in solution using calibrated glass electrode system. |
| Specific Optical Rotation | [alpha]D | Determines enantiomeric purity by measuring rotation of plane-polarized light at 589 nm. |
| Related Substances | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities using reversed-phase C18 column and UV detection. |
| Residual Solvents (e.g., Ethanol, Acetone) | Gas Chromatography (GC) with FID | Detects and quantifies volatile organic solvents by separation on capillary column and flame ionization detection. |
| Microbial Limits | Membrane Filtration and Plate Count | Estimates viable aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration. |
