| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and presence of visible impurities under natural light or standard illumination. |
| Purity (Content) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (e.g., 254 nm), and determine the main component content using external standard method or area normalization. |
| Melting Point | Capillary Melting Point Method | Fill the sample into a capillary tube and gradually heat it in a melting point apparatus. Record the initial and final melting temperatures to assess purity and characteristic properties. |
| Moisture Content | Karl Fischer Titration | Use the quantitative reaction between iodine and sulfur dioxide in a methanol/water system to determine trace amounts of water, suitable for compounds containing active hydrogens. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Optimize chromatographic conditions to separate the main peak and impurity peaks, detect and quantify synthetic by-products and degradation products. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH guidelines, detect residual organic solvents (such as methanol, ethanol, acetone, dichloromethane, etc.) from the production process. |
| Sulfur Content (Thiol Verification) | Elemental Analysis or Redox Titration | Determine sulfur content using an elemental analyzer, or use iodometric titration to verify the presence and content of —SH groups. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine the residual levels of toxic heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeia or environmental regulations. |
| Solubility | Solubility Test | Add a certain amount of sample to a specified solvent (such as water, ethanol, acetone, etc.), observe its solubility, and evaluate process applicability. |
| Polymorphic Analysis | X-ray Powder Diffraction (XRD) | Analyze the crystal structure of solid samples to confirm whether multiple polymorphs exist, used for consistency control and stability studies. |
| Infrared Spectroscopy (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Confirm functional groups in the molecular structure (such as —NH₂, —SH, C=N, triazine ring, etc.) through characteristic absorption peaks for qualitative identification. |
