Manufacturing Quality Control of alpha-Hydroxybenzenepropanoic acid methyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration standard using flame ionization detection. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separates L- and D-enantiomers on a chiral stationary phase; ee calculated from peak area ratio. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by equilibrium partitioning into headspace followed by GC analysis. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification via plasma ionization and mass spectrometric detection at trace levels. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride anions after suppressed ion chromatography. |
| Residual Methanol | Gas Chromatography (GC) with FID | Direct injection GC analysis targeting methanol peak using external calibration. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard white background under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary method. |
| Specific Optical Rotation | [a]D Measurement | Quantifies rotation of plane-polarized light at 589 nm using sodium lamp and temperature-controlled cell. |
| Related Substances (Impurities) | HPLC with UV Detection | Separation on reversed-phase column; detection and quantification of impurities relative to main peak at 210–230 nm. |
