Manufacturing Quality Control of 2-Methylthio-4-pyrimidinol
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities under natural light or standard illumination. |
| Purity and Active Ingredient Content | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase column (e.g., C18) with a UV detector (typically at 260–280 nm wavelength); qualitative identification is based on retention time, and quantitative analysis is performed via external standard calibration using peak area. Effectively separates impurities and accurately determines target compound content. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Perform structural analysis using ¹H-NMR and ¹³C-NMR to assign hydrogen and carbon signals corresponding to the methylthio group and pyrimidine ring, verifying the molecular structure. |
| Structure Confirmation | Mass Spectrometry (MS) | Employ electrospray ionization (ESI) or electron ionization (EI) mass spectrometry to determine molecular ion peaks ([M+H]+ or M•+) and analyze fragment ion patterns for molecular weight confirmation. |
| Water Content | Karl Fischer Titration | Utilize the quantitative reaction of iodine and sulfur dioxide in the presence of pyridine and methanol with water; measure water content via coulometric titration, suitable for trace moisture analysis. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH guidelines, use a capillary column and FID detector to identify and quantify residual organic solvents (e.g., methanol, ethanol, acetone) potentially present from manufacturing processes. |
| Melting Point | Melting Point Determination (Capillary Method) | Load the sample into a capillary tube and gradually heat it in a melting point apparatus; observe the initial and complete melting temperatures for identification and preliminary purity assessment. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and measure residual levels of heavy metal elements such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopeial or safety limits. |
| Related Substances (Impurities) | HPLC-UV or LC-MS | Separate degradation products or synthetic by-products using gradient elution; identify and quantify individual impurities using UV or mass spectrometry detectors to evaluate sample stability and process purity. |
| Particle Size Distribution (if solid) | Laser Diffraction Particle Size Analysis | Disperse the sample in a liquid or gas medium and determine particle size distribution based on laser diffraction principles; applicable for pre-formulation studies. |
