Manufacturing Quality Control of 212322-56-0
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with reference spectra to confirm the presence of characteristic functional groups (e.g., amide, amino, ester, pyridine ring), used for structural confirmation of compounds. |
| Identification | High-Performance Liquid Chromatography (HPLC) | Compare the retention time of the main peak of the test sample with that of a reference standard under specific chromatographic conditions, used for preliminary identification of the target compound. |
| Identification | Mass Spectrometry (MS) or Liquid Chromatography-Mass Spectrometry (LC-MS) | Determine the molecular ion peak and fragment ions to verify molecular weight and structural characteristics, providing highly specific identification evidence. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with an appropriate mobile phase (e.g., acetonitrile-buffer system) under isocratic or gradient elution; determine the content of the active ingredient by external or internal standard method. This is the most commonly used quantitative method in quality control. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employ a high-sensitivity HPLC method (typically gradient elution) to separate and detect process-related impurities and degradation products. Quantify individual impurities using area normalization or relative response factor methods. |
| Residual Solvents | Gas Chromatography (GC) | Using headspace or direct injection, separate components on a capillary column and detect with an FID detector to quantitatively determine residual organic solvents such as methanol, ethanol, dichloromethane, ethyl acetate, etc. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Atmospheric Pressure Drying Method | Dry the sample at a specified temperature (e.g., 105°C) to constant weight and measure the percentage loss in mass due to water or other volatile components, assessing the degree of dryness of the sample. |
| Sulfated Ash (Residue on Ignition) | Gravimetric Method | Ignite the sample at high temperature (approximately 700–800°C) and weigh the residual inorganic matter to monitor inorganic impurities (e.g., metal catalyst residues). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, determine the levels of heavy metal elements such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeial or ICH Q3D limits. |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration and measure its acidity or alkalinity using a calibrated pH meter, reflecting the influence of free acid/base or salt forms. |
| Specific Optical Rotation (for chiral compounds) | Polarimetry | If the compound contains a chiral center and optical purity needs to be controlled, measure its specific optical rotation at a specified wavelength (e.g., sodium D line) and temperature for quality control purposes. |
