Manufacturing Quality Control of 2,4-Pyridinedicarboxylic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and visible impurities under natural light or standard illumination. Suitable for preliminary assessment of solid samples. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature range using a melting point apparatus; compare with reference values (literature value approximately 215–217 °C, decomposition) to assess purity. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with phosphate buffer-methanol as mobile phase, UV detector (~254 nm), and external standard method for quantitative determination of the main component. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Same as above; employ gradient elution to separate the main peak from impurity peaks, calculate area percentages of each impurity peak to evaluate purity and total impurity levels. |
| Infrared Spectroscopy Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Determine infrared absorption spectrum by preparing KBr pellets or using ATR method; compare with reference spectra to confirm functional group consistency. |
| Water Content | Karl Fischer Titration | Determine moisture content using coulometric or volumetric Karl Fischer methods, suitable for precise control of loss on drying specifications. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at a specified temperature (e.g., 105 °C) to constant weight; calculate the percentage of weight loss to assess volatile impurities or residual solvents. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | After high-temperature incineration, treat residue with sulfuric acid and weigh the remaining inorganic matter to evaluate inorganic impurity content. |
| pH Value | pH Meter Measurement | Measure the acidity or alkalinity of a solution (e.g., 1% w/v) using a pH meter; should fall within expected range (typically slightly acidic). |
| Heavy Metals | Sulfide Colorimetry (Pharmacopoeial Method) | Follow procedures outlined in Chinese Pharmacopoeia or USP; detect heavy metals such as lead via sodium sulfide color development and subsequent color comparison. |
| Nuclear Magnetic Resonance (Structural Confirmation) | ¹H-NMR and ¹³C-NMR | Dissolve sample in deuterated solvent (e.g., DMSO-d6), perform proton and carbon NMR analyses to verify molecular structure accuracy. |
