Manufacturing Quality Control of Dimethyl 3-hydroxyglutarate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid groups by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by weight difference after high-temperature ashing at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Identifies and quantifies structurally related impurities based on retention time and UV absorbance relative to main peak. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against standard reference under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Determination | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
| Residual Solvents (Methanol, DMF) | Headspace Gas Chromatography (HS-GC) | Quantifies volatile organic solvents by equilibrium partitioning into headspace followed by GC-FID analysis. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment, indicating metal salt impurities. |
