Manufacturing Quality Control of (S)-(+)-2-Phenylglycinol
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 chromatographic column and a UV detector (typically at 210–230 nm), the content of L-phenylglycine alcohol is determined using external or internal standard methods, offering high sensitivity and good repeatability. |
| Enantiomeric Purity | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Using chiral stationary phase columns (such as Chiralpak AD-H, AS-H, etc.), L- and D-enantiomers are separated to evaluate enantiomeric excess (ee value), ensuring optical purity. |
| Related Substances/Impurities | High-Performance Liquid Chromatography (HPLC) | Under gradient or isocratic elution conditions, synthetic intermediates, by-products, or degradation impurities are detected. Quantification is performed using peak area normalization or reference substance method. |
| Moisture | Karl Fischer Titration | Based on the reaction between iodine and sulfur dioxide with water in an anhydrous environment, this method accurately determines the moisture content in the sample, suitable for quality control of raw materials. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH guidelines, residual organic solvents (such as methanol, ethanol, ethyl acetate, etc.) from the production process are detected. Headspace sampling is used to improve sensitivity and accuracy. |
| Melting Point | Melting Point Determination (Capillary Method) | Using a melting point apparatus, the temperature range at which the sample transitions from solid to liquid is measured, used for preliminary identification and purity assessment. The typical melting point of L-phenylglycine alcohol is approximately 68–72°C. |
| Specific Rotation | Polarimetry | The optical rotation of a solution is measured under the sodium D-line (589 nm), and specific rotation [α]D is calculated, used to confirm its optical activity and configuration (L-type is typically levorotatory). |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectrometry (AAS) | Detection of harmful metal elements such as lead, cadmium, mercury, meeting the strict requirements of pharmacopoeias for injectable or pharmaceutical raw materials. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | The percentage of mass loss is determined after heating the sample at a specified temperature for a certain time, used to evaluate volatile components and adsorbed moisture. |
| Ignition Residue | Sulfuric Acid Ashing Method | The sample is carbonized at high temperature and then further ashed with sulfuric acid until constant weight is achieved, determining the total amount of non-volatile inorganic impurities. |
