Manufacturing Quality Control of OCTAHYDROCOUMARIN
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity Determination | High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column with a UV detector (e.g., 210–220 nm); quantification is performed using external standard or area normalization methods to assess the purity of the main component. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Confirms molecular structure by analyzing chemical shifts and coupling constants of hydrogen and carbon atoms using ¹H-NMR and ¹³C-NMR. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Suitable for detecting volatile impurities; unknown impurities are identified via mass spectral library matching and quantified based on retention time. |
| Water Content | Karl Fischer Titration (KF Method) | Employs electrochemical titration to precisely measure trace amounts of water in samples, complying with pharmacopoeial or chemical industry standards. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Sample is heated to generate headspace vapor, which is then sampled and separated via a capillary column; residual organic solvents (e.g., methanol, ethyl acetate) are quantified using FID or MS detectors. |
| Melting Point Determination | Digital Melting Point Apparatus | An automated melting point instrument is used to observe the temperature range from initial to complete melting, assessing substance purity and crystal form consistency. |
| Optical Rotation / Specific Rotation | Automatic Polarimeter | For chiral compounds, optical rotation is measured at a specific wavelength (typically 589 nm) to control optical purity. |
| Appearance and Color | Visual Color Comparison / Colorimeter | Sample color is compared with a reference standard under standardized lighting conditions, either visually or using a colorimeter, to ensure compliance with appearance specifications. |
| Loss on Drying | Drying Weight Loss Method | Sample is dried at a specified temperature (e.g., 105°C) until constant weight is achieved; the percentage of mass loss is calculated to evaluate the content of volatile components. |
| Heavy Metal Residues | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After acid digestion of the sample, ICP-MS is used for highly sensitive detection of heavy metal residues such as lead, cadmium, mercury, and arsenic. |
