Manufacturing Quality Control of (S)-(-)-Methyl 2-chloropropionate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Optical Rotation | [alpha]D Measurement using Polarimeter | Measures the angle of rotation of plane-polarized light caused by chiral molecules in solution at specified concentration and temperature. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents are vaporized in sealed vials, then quantified by GC-FID or GC-MS using calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Chloride Ion Impurity | Ion Chromatography (IC) | Separation of anions on an ion-exchange column followed by conductivity detection; quantified against chloride calibration standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification after acid digestion, using isotopic mass spectrometry for high sensitivity and specificity. |
| Residual Methanol | Gas Chromatography (GC) with FID | Direct injection and separation on a wax or polyethylene glycol column; quantified using external methanol standard. |
| Related Substances | GC-MS or HPLC-UV | Separation of structurally related impurities followed by detection and semi-quantitative or quantitative assessment relative to main peak. |
| Appearance | Visual Inspection | Assessment of liquid clarity and color against water-white standard under controlled lighting and viewing conditions. |
| Density | Digital Density Meter | Measurement of sample density at 20 degrees C using oscillating U-tube principle with temperature-controlled Peltier system. |
| Refractive Index | Digital Refractometer | Determination of refractive index at 20 degrees C by measuring critical angle of total internal reflection. |
