Manufacturing Quality Control of 4,6-Dichloro-2-pyridinecarboxylic acid
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample color, form (e.g., white to off-white crystalline powder), and check for foreign matter or moisture absorption/clumping. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with buffer/solvent as the mobile phase and a UV detector (e.g., 254 nm) for quantifying the main component. Calculate using external standard method or area normalization method. |
| Related Substances (Impurities) | HPLC Method (Gradient Elution) | Use a high-sensitivity HPLC system with gradient elution to separate potential process impurities and degradation products. Control impurity limits by relative retention time and peak area. |
| Loss on Drying | Oven-Drying Method (Pharmacopoeia General Chapter 0831) | Dry the sample at 105°C until constant weight is achieved, calculate the percentage mass loss to control moisture and volatile substances content. |
| Ignition Residue | High-Temperature Ashing Method (Pharmacopoeia General Chapter 0841) | The sample is carbonized with sulfuric acid and then incinerated in a high-temperature furnace at 700–800°C. Weigh the remaining inorganic residue to assess total inorganic impurities. |
| Residual Solvents | Gas Chromatography (GC, Headspace Injection) | According to ICH Q3C, use a capillary column + headspace injection + FID detector to quantify residual organic solvents such as methanol, ethanol, DMF, etc. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | After sample digestion, use atomic absorption or inductively coupled plasma mass spectrometry to determine trace elements such as lead, arsenic, cadmium, mercury, etc. |
| pH Value | pH Meter Measurement | Prepare a water solution of specific concentration (e.g., 1%), calibrate the pH meter, and directly measure the pH to evaluate acidity/alkalinity compliance. |
| Melting Point | Capillary Melting Point Apparatus | Measure initial and final melting points according to pharmacopoeial specifications at a defined heating rate to verify compound purity and crystal form consistency. |
| Water Content | Karl Fischer Titration Method | Use volumetric or coulometric Karl Fischer titration instruments to accurately determine trace water content in the sample, especially suitable for water-sensitive products. |
