Manufacturing Quality Control of METHYL (S)-(+)-3-HYDROXY-2-METHYLPROPIONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area against reference standard. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separates (S)- and (R)-enantiomers on chiral stationary phase; ee calculated from peak area ratio. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in methanol-based solvent. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects volatile solvents (e.g., methanol, toluene) by equilibrium partitioning into headspace before GC analysis. |
| Acid Value | Acid-Base Titration with NaOH | Measures free acid impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Specific Optical Rotation | [a]D Measurement using Polarimeter | Determines optical activity at 589 nm to confirm chiral integrity and identity of (S)-(+)-enantiomer. |
| Heavy Metals | ICP-OES | Quantifies trace metals (e.g., Pb, Cd, Ni) after acid digestion by plasma emission spectroscopy. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established visual standards under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Related Substances | HPLC with UV Detection | Identifies and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, confirming identity and purity. |
