Manufacturing Quality Control of 167316-27-0
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state (such as white to off-white powder) of the sample, and check for caking or visible impurities. |
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 chromatographic column with a UV detector (usually at 254 nm or 220 nm), determine the purity of the target compound using external standard method or area normalization method. |
| Chiral Purity | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Use chiral stationary phase chromatographic columns (such as Chiralpak AD-H, OD-H, etc.), separate enantiomers, and evaluate enantiomeric excess (ee value). |
| Melting Point | Melting Point Determination Method (Capillary Method or Automatic Melting Point Analyzer) | Determine the temperature range at which the compound changes from solid to liquid, used to initially assess its purity and consistency. |
| Moisture Content | Karl Fischer Titration (Karl Fischer) | Quantitatively determine the moisture content in the sample using KF reagent. It includes volumetric and coulometric methods, suitable for trace moisture detection. |
| Residual Solvents | Gas Chromatography (GC) | Detect residual organic solvents (such as methanol, ethanol, ethyl acetate, dichloromethane, etc.) during production according to ICH guidelines. |
| Sulfate Ash / Residue on Ignition | Ignition Residue Method | After high-temperature ignition, weigh the residue to assess the content of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detect the residual amounts of toxic heavy metals such as lead, mercury, cadmium, and arsenic to ensure compliance with pharmacopoeia or safety standards. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Use ¹H NMR and ¹³C NMR to confirm the structure of the compound and verify the position of substituents and stereochemistry. |
| Structure Confirmation | Mass Spectrometry (MS) | Determine the molecular ion peak through ESI-MS or EI-MS to confirm molecular weight and fragment information, assisting in structural identification. |
| Specific Rotation | Optical Rotatory Dispersion Method | Measure the optical rotation of the solution under sodium light D line (589 nm) and calculate specific rotation, used to verify optical purity and configuration. |
