| Fine Chemicals | Production of epoxy resins | Condensation reaction |
| Pesticide Industry | Production of pesticide intermediates | Condensation reaction |
Manufacturing Quality Control of (S)-Oxiranemethanol
| Test Item | Common Detection Method | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 chromatographic column and a UV detector (e.g., 210 nm), with water-organic solvent (e.g., methanol or acetonitrile) as the mobile phase, to quantitatively analyze (S)-glycidol. Suitable for precise content determination of high-purity samples. |
| Purity and Impurity Analysis | Gas Chromatography (GC) | Using polar or moderately polar capillary columns (e.g., DB-WAX), with a FID detector, separating the main component from organic impurities (e.g., alcohols, ethers) based on volatility differences. Appropriate for volatile sample systems. |
| Enantiomeric Purity | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Using chiral stationary phase columns (e.g., Chiralpak AD-H, AS-H), under normal-phase conditions (hexane-isopropanol mobile phase) to separate (R) and (S) enantiomers, evaluating enantiomeric excess (ee value). |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyzing characteristic peaks via ¹H NMR and ¹³C NMR to confirm the molecular structure and stereochemistry of (S)-glycidol. Commonly used for raw material identification and impurity structure inference. |
| Residual Solvents | Headspace-Gas Chromatography (HS-GC) | Heating the sample in a sealed container to reach equilibrium, detecting volatile organic solvents (e.g., methanol, ethanol, acetone) residues, complying with ICH Q3C guideline requirements. |
| Water Content | Karl Fischer Titration (KF) | Divided into volumetric or coulometric methods, precisely determining trace moisture in the sample, avoiding hydrolysis of the epoxy group and ensuring stability. |
| Epoxy Group Reactivity | Epoxy Value Titration | Using the hydrochloric acid-pyridine method or perchloric acid method under specific conditions to open the ring, calculating the epoxy equivalent by titrating unreacted acid, indirectly reflecting the content of reactive groups. |
