| Industry | Application | Process |
|---|---|---|
| Veterinary Medicine | Antibacterial agent | Used to treat bacterial infections in animals, including swine, cattle, and poultry |
| Feed Additives | Prevention and control of animal intestinal infections | Incorporated into animal feed to prevent the spread of bacterial diseases |
| Pharmaceuticals | Chemical for R&D | Served as an intermediate or research material in the synthesis of other sulfonamide drugs |
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectrophotometry (IR) | By measuring the infrared absorption spectrum of the sample and comparing it with the standard spectrum, the characteristic functional groups and molecular structure of sulfamethoxydiazine sodium can be confirmed. |
| Identification | High-Performance Liquid Chromatography (HPLC) | Under specified chromatographic conditions, compare the retention time of the main peak in the test sample with that of the reference standard for qualitative identification. |
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Determine the maximum absorption of the sample at specific wavelengths (e.g., approximately 265 nm and 310 nm) and compare with the absorption characteristics of the reference standard for identification. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 column, with phosphate buffer-methanol or acetonitrile as the mobile phase, and a UV detector to detect the analyte. The content is calculated using the external standard method, which is the main quantitative method recommended by the pharmacopoeia. |
| Related Substances (Impurity Check) | High-Performance Liquid Chromatography (HPLC) | Using gradient or isocratic elution to separate and detect possible process impurities and degradation products, with impurity limits controlled by area normalization or self-reference methods. |
| Loss on Drying | Thermogravimetric Analysis / Drying Method | The sample is dried at a specified temperature (e.g., 105°C) until constant weight is achieved, and the mass loss is measured to evaluate the content of moisture and volatile substances. |
| Residue on Ignition | Ignition Method | The sample is ignited at high temperature (usually 700–800°C), and the remaining inorganic residue is weighed to control inorganic impurities. |
| pH Value | pH Meter Method | A solution of defined concentration is prepared, and its acidity or alkalinity is measured using a calibrated pH meter to ensure compliance with the pharmacopoeia-specified range (usually pH 6.0–8.0). |
| Solution Clarity and Color | Visual Turbidity/Color Comparison or Spectrophotometry | Observe whether the sample solution is clear and free of foreign matter, and compare it with standard turbidity/color reference solutions to assess purity. |
| Heavy Metals | Thioacetamide Method (Colorimetry) or ICP-MS | Determine the total or individual content of heavy metal elements such as lead, cadmium, mercury, and arsenic via colorimetric reaction or inductively coupled plasma mass spectrometry (ICP-MS) to ensure compliance with safety limits. |
