Manufacturing Quality Control of 748788-39-8
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Chemical Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Utilizing ¹H NMR and ¹³C NMR to analyze chemical shifts, coupling constants, etc., to confirm molecular framework and substitution positions. |
| Molecular Weight Confirmation | Mass Spectrometry (MS) | Using ESI-MS or EI-MS to determine molecular ion peaks, verifying the molecular weight of the target compound and fragmentation patterns, supporting structural elucidation. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Employing C18 reversed-phase columns with UV detection (e.g., 254 nm), assessing main component purity and impurity levels based on retention time and peak area. |
| Impurity Limit Testing | HPLC or UPLC | Comparing with reference standards to establish impurity profiles, quantifying known and unknown impurities, complying with ICH Q3A/B impurity control requirements. |
| Residual Solvent Detection | Gas Chromatography (GC) | Using headspace or direct injection with FID detection; quantifying residual organic solvents according to pharmacopoeial methods (e.g., USP <467>). |
| Moisture Content | Karl Fischer Titration | Applying volumetric or coulometric methods to accurately determine trace moisture in samples, ensuring compliance with stability and formulation processing requirements. |
| Melting Point Determination | Capillary Melting Point Apparatus | Observing the temperature range from initial melting to complete melting during heating, serving as a physical constant for preliminary identification and purity assessment. |
| Heavy Metal Testing | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Digesting samples and measuring residual levels of lead, cadmium, mercury, arsenic, etc., in accordance with ICH Q3D guideline on elemental impurities. |
| Polymorph/ Crystalline Form Analysis | X-Ray Powder Diffraction (XRPD) | Comparing diffraction patterns with standard crystalline forms to ensure batch-to-batch consistency of crystal form, which affects solubility and stability. |
| Thermal Stability / Decomposition Behavior | Differential Scanning Calorimetry (DSC) or Thermogravimetric Analysis (TGA) | DSC detects phase transitions/melting temperatures; TGA monitors weight loss, evaluating thermal stability and potential degradation temperature ranges. |
