Manufacturing Quality Control of N,9-Diacetylguanine
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and visible impurities under natural light or standard illumination to determine compliance with specified characteristics. |
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase C18 column with gradient or isocratic elution using water and organic solvents (e.g., methanol or acetonitrile), detected by UV detector (around 254 nm). Quantify the main peak purity using external standard method or area normalization. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Use ¹H-NMR and ¹³C-NMR to analyze molecular structure, confirming the substitution position at N,9-di-acetyl and overall structural consistency. |
| Structural Confirmation | Mass Spectrometry (MS) | Employ electrospray ionization (ESI) or electron impact (EI) mass spectrometry to determine molecular ion peaks, confirming molecular weight and fragmentation patterns. |
| Water Content | Karl Fischer Titration | Quantitatively determine water content via iodine reaction with sulfur dioxide in pyridine and methanol system, using coulometric titration for high precision. |
| Residual Solvents | Gas Chromatography (GC) | Test for residual organic solvents (e.g., ethyl acetate, methanol, dichloromethane) from manufacturing processes according to ICH guidelines, using FID detection. |
| Melting Point | Melting Point Determination (Capillary Method) | Determine the temperature range from initial melting to complete melting using a melting point apparatus or capillary method, used for identification and preliminary purity assessment. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use HPLC to detect process-related impurities and degradation products; typically apply gradient elution to separate individual impurity peaks and calculate total impurity levels. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Method | Measure mass loss after heating the sample at a specified temperature for a defined period, assessing volatile components or solvent residues. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | Treat the sample with sulfuric acid followed by high-temperature ignition, then weigh the remaining inorganic residue to assess inorganic impurity levels. |
