Manufacturing Quality Control of 5-Methyl-2-pyrazinecarboxylic acid
| Test Item | Common Test Method | Method Description |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with reference spectra to confirm characteristic functional groups of 5-methylpyrazine-2-carboxylic acid (such as carboxyl group, pyrazine ring, etc.) by their absorption peak positions and intensities, for structural confirmation. |
| Identification | Proton Nuclear Magnetic Resonance (¹H NMR) | Use NMR technology to measure chemical shifts, coupling constants, and integration areas of hydrogen atoms in the sample. Compare with theoretical or standard spectra to verify molecular structural features. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Employ a reversed-phase C18 column with a suitable mixture of water and organic solvent (e.g., methanol or acetonitrile) as the mobile phase. Detection is performed using a UV detector (typically around 254 nm). The content of the main component is calculated via external standard or internal standard method, offering high sensitivity and good reproducibility. |
| Related Substances / Impurity Testing | High-Performance Liquid Chromatography (HPLC) | Similar to assay determination, but with optimized chromatographic conditions (e.g., gradient elution) to achieve effective separation of the main peak from potential impurities (such as synthesis intermediates or degradation products). Impurity limits are controlled using the area normalization method or a main component self-reference method with correction factors. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Temperature Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, then determine the percentage of mass loss, used to control moisture and volatile matter content. |
| Sulfated Ash / Residue on Ignition | High-Temperature Ashing Method | The sample is charred and then ignited in a high-temperature furnace at 700–800°C. The remaining inorganic residue is weighed to determine the total inorganic impurity content. |
| pH Value | pH Meter Method | Dissolve the sample into an aqueous solution of defined concentration (e.g., 1%), and measure its acidity or alkalinity using a calibrated pH meter to reflect the presence of free acid forms. |
| Melting Point | Capillary Melting Point Method | Measure the temperature range from initial melting to complete melting using a melting point apparatus. Compare with literature values (approximately 180–183°C) as an auxiliary indicator of purity and crystalline form. |
