| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Compare the sample spectrum with a reference standard spectrum; confirm molecular structure through characteristic absorption peaks to verify authenticity. |
| High-Performance Liquid Chromatography (HPLC) | Compare retention time with a reference standard to confirm consistency of the main peak, used as an auxiliary identification method. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase C18 column with a UV detector (typically around 220 nm); quantify the main component using external or internal standard methods, offering high accuracy and good reproducibility. |
| Acid-Base Titration | Utilize the carboxyl group in tranexamic acid; titrate with a standard alkaline solution in a non-aqueous medium, suitable for assay of active pharmaceutical ingredients. | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate impurity peaks using gradient elution to detect degradation products or synthetic intermediates; calculate individual and total impurity levels in compliance with pharmacopoeial requirements. |
| Solution Clarity | Visual Turbidity Comparison | Dissolve the sample in water and compare with a standard turbidity solution to determine the presence of insoluble particles. |
| Solution Color | Visual Color Comparison / UV-Vis Spectrophotometry | Compare with standard color solutions, or scan in the visible light range to assess whether the solution color meets specified requirements. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample to constant weight under specified conditions and measure the percentage weight loss to determine content of crystalline water or residual solvents. |
| Residue on Ignition | Residue on Ignition Test | Ignite the sample at high temperature and weigh the residual inorganic material to evaluate the level of inorganic impurities. |
| Heavy Metals | Thioacetamide Method (Chinese Pharmacopoeia) | Under weakly acidic conditions, heavy metals react with thioacetamide to form colored precipitates; perform a colorimetric limit test. |
| Related Substances (Chiral Impurities) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Use a chiral chromatographic column to separate enantiomers and detect the presence of optical impurities to ensure stereochemical purity. |
| Residual Solvents | Gas Chromatography (GC) | Employ headspace sampling to detect residual organic solvents (e.g., methanol, ethanol, acetone) from the manufacturing process, in compliance with ICH limit requirements. |
