Manufacturing Quality Control of 2,3-Pyrazinedicarboxylic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity Determination | High-Performance Liquid Chromatography (HPLC) | Utilizes reversed-phase columns (e.g., C18), with phosphate buffer or acetonitrile/water as the mobile phase, and UV detection (e.g., 254 nm) for quantitative analysis of the main component's purity. Suitable for accurately determining the content of the target compound and impurity levels in samples. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Employs ¹H NMR and ¹³C NMR to analyze chemical shifts and coupling constants of hydrogen and carbon atoms, confirming the structural integrity and substitution positions of 2,3-pyrazinedicarboxylic acid. |
| Functional Group and Structural Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Identifies characteristic absorption peaks (e.g., carboxyl C=O stretching vibration ~1700 cm⁻¹, pyrazine ring skeletal vibrations ~1600–1500 cm⁻¹) to verify the presence of functional groups and molecular structural consistency. |
| Impurity Analysis | Ultra-Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS) | Combines high separation efficiency with mass spectrometry for qualitative and quantitative identification of trace organic impurities (e.g., synthesis by-products, degradation products), enhancing accuracy in impurity profiling. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Drying Loss Method | Measures weight loss percentage after heating samples under specified conditions (e.g., 105°C), assessing moisture and volatile substance content to meet pharmacopeial or industrial standards. |
| Melting Point Determination | Capillary Melting Point Apparatus Method | Determines the temperature range from initial to complete melting during heating, serving as a physical constant quality indicator; pure substances exhibit narrow melting ranges. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Uses headspace injection coupled with FID or MS detection to quantitatively analyze residual organic solvents (e.g., methanol, ethanol, DMF) from manufacturing processes, complying with ICH Q3C guidelines. |
| Heavy Metal Limits | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, detects levels of heavy metals such as lead, cadmium, mercury, and arsenic, ensuring compliance with safety limits for pharmaceutical or industrial raw materials. |
