Manufacturing Quality Control of (1S,2S,3R,5S)-(+)-2,3-Pinanediol
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm functional groups and molecular structural features. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze hydrogen atoms' chemical shifts, coupling constants, and integration areas to verify stereochemistry and structural consistency. | |
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Separate using a reverse or normal-phase chromatographic column and quantify the main component with UV or differential refractive index detection to calculate purity or content. |
| Gas Chromatography (GC) | Suitable for volatile derivatives (e.g., silylated products), qualitative by retention time and quantitative by peak area. | |
| Enantiomeric Purity/Optical Purity | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Use a chiral stationary phase column to separate enantiomers and evaluate optical purity of the target configuration (1S,2S,3R,5S). |
| Optical Rotation Measurement | Determine the specific optical rotation of the sample at a specific wavelength (usually sodium D line, 589 nm) and compare it with theoretical values to assess optical purity. | |
| Residual Solvents | Gas Chromatography (GC) | Headspace or direct injection methods are used to detect residual organic solvents (e.g., methanol, ethanol, acetone) from the production process. |
| Moisture | Karl Fischer Titration | Quantitatively determine moisture content in the sample using the iodine-sulfur dioxide reaction, suitable for trace moisture detection. |
| Melting Point | Melting Point Determination | Determine the melting temperature range using capillary method or automatic melting point instrument as a physical constant for auxiliary identification and purity assessment. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detect residual harmful heavy metal elements such as lead, arsenic, mercury, and cadmium in the sample to ensure compliance with pharmacopoeia or safety standards. |
| Ignition Residue/ash | Gravimetric Analysis after Incineration | Weigh the inorganic residue mass after high-temperature incineration to evaluate total inorganic impurities. |
