Manufacturing Quality Control of 6-Hydroxy-5-nitronicotinic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Inspect the sample by eye for color, physical state (e.g., white to off-white crystalline powder), and presence of foreign particles to determine compliance with specifications. |
| Identification | Infrared Spectroscopy (IR) High-Performance Liquid Chromatography (HPLC) |
IR: Measure the infrared absorption spectrum of the sample and compare it with a reference spectrum to confirm the presence of characteristic functional groups (e.g., nitro, carboxyl, hydroxyl, pyridine ring). HPLC: Compare the retention time of the test sample with that of the reference standard under specified chromatographic conditions. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase consisting of a suitable mixture of buffer and organic solvent (e.g., phosphate buffer-methanol or acetonitrile). Detection is performed using a UV detector, typically at 254 nm or at the compound’s maximum absorbance wavelength. The assay is calculated using an external standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employ either gradient or isocratic elution to separate the main peak from potential impurities (e.g., starting materials, intermediates, degradation products). Individual and total impurity levels are controlled using area normalization or a corrected principal component self-reference method. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Temperature Atmospheric Drying | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved. The percentage weight loss is measured to control moisture and volatile substances. |
| Sulfated Ash (Residue on Ignition) | High-Temperature Incineration | The sample is charred and then ignited in a high-temperature furnace at 700–800°C. The weight of the residual inorganic matter is measured to assess inorganic impurities (e.g., metal salts). |
| Residual Solvents | Gas Chromatography (GC) | Using headspace or direct injection, separate components on a capillary column and detect with an FID. Measures residual organic solvents (e.g., methanol, ethanol, dichloromethane) possibly remaining from manufacturing. Limits are controlled according to ICH Q3C guidelines. |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v) and measure its pH using a calibrated pH meter, reflecting the ionization characteristics of carboxylic acid and phenolic hydroxyl groups. |
| Melting Point | Capillary Melting Point Method | Determine the temperature range from initial melting to complete melting using a melting point apparatus. Serves as an auxiliary indicator of purity and crystal form. |
