Manufacturing Quality Control of 4-Amino-6-chlorobenzene-1,3-disulfonamide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at 254 nm. |
| Moisture Content | Karl Fischer titration | Volumetric or coulometric titration measuring water content via stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol/pyridine medium. |
| Residue on Ignition | Gravimetric analysis | Determination of non-volatile inorganic impurities by ignition at 700-800 C and weighing the residual ash. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Potentiometric titration with silver nitrate | Titration using AgNO3 solution and silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate Impurity | Gravimetric analysis with barium chloride | Precipitation of sulfate as BaSO4 under controlled acidic conditions, followed by filtration, drying, and weighing. |
| Related Substances | HPLC with diode array detection | Separation and identification of structurally related impurities using gradient reversed-phase HPLC and spectral comparison. |
| Melting Point | Capillary melting point apparatus | Thermal transition measurement where solid phase converts to liquid; determined by observing temperature range of complete fusion. |
| pH of Aqueous Solution | Potentiometric pH measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode and reference electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents using capillary GC column and flame ionization detection. |
