Manufacturing Quality Control of 6,7-Bis-(2-methoxyethoxy)-4(3H)-quinazolinone
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of visible foreign particles under natural light or standard illumination. |
| Identification | Infrared Spectroscopy (IR) | Compare the sample spectrum with reference spectra; identify functional groups based on characteristic absorption peaks to confirm molecular structure and verify authenticity. |
| Nuclear Magnetic Resonance Spectroscopy (¹H-NMR or ¹³C-NMR) | Analyze chemical shifts, coupling constants, and integration areas of hydrogen or carbon signals to confirm molecular structural consistency. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use reversed-phase columns (e.g., C18), detect at ~254 nm using UV detector, and quantify the main component by external standard or internal standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak from impurity peaks using gradient or isocratic elution; calculate area percentages of impurity peaks to assess purity and compliance with impurity limits. |
| Residual Solvents | Gas Chromatography (GC) | Follow ICH guidelines to detect organic solvents (e.g., methanol, ethanol, dichloromethane) potentially remaining from manufacturing processes; use FID detector for quantification. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight; calculate moisture and volatile content based on mass loss. |
| Residue on Ignition (Ash Content) | Sulfation followed by High-Temperature Incineration | Add sulfuric acid, then incinerate at 500–600°C until constant weight; determine the amount of non-volatile inorganic impurities. |
| Moisture Content | Karl Fischer Titration | Utilize the reaction between iodine and sulfur dioxide in an anhydrous environment with water; precisely measure trace amounts of moisture, suitable for low-moisture samples. |
| Melting Point | Capillary Melting Point Method | Fill the sample into a capillary tube and gradually heat it in a heating bath; record initial and final melting temperatures to assess purity and physical characteristics. |
| Solubility | Visual Dissolution Test | Add a defined amount of sample to different solvents (e.g., water, ethanol, DMSO), shake, and visually observe dissolution behavior to evaluate solubility performance in various solvents. |
| Polymorphic Analysis (if applicable) | X-Ray Powder Diffraction (XRPD) | Analyze crystal diffraction patterns to identify different polymorphic forms and ensure batch-to-batch consistency, especially relevant when the active pharmaceutical ingredient exhibits multiple polymorphs. |
| Particle Size Distribution (for solid raw materials) | Laser Particle Size Analysis (LPA) | Determine particle size distribution using laser scattering principles; affects dissolution rate and formulation performance; commonly used for pre-formulation assessment of raw materials. |
