Manufacturing Quality Control of 4-Amino-2,5-dichlorobenzenesulfonic acid
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities in the sample under natural light or standard lighting conditions. |
| Assay (Content Determination) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (typically around 254 nm), employing a mobile phase consisting of water-organic solvent (e.g., methanol or acetonitrile) with ion-pair reagents or buffer salts. Quantify the main component using external or internal standard methods. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Same as above; assess peak purity by area normalization method and identify and quantify impurity peaks. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Optimize gradient elution programs to detect potential impurities such as synthesis intermediates, by-products, degradation products, unreacted starting materials, or oxidation products. |
| Water Content | Karl Fischer Titration | Determine the amount of crystalline or adsorbed water precisely using coulometric or volumetric Karl Fischer titrator. |
| Melting Point | Capillary Melting Point Method | Pack sample into a capillary tube and gradually heat in a melting point apparatus; record initial and final melting temperatures to assess compound purity and consistency. |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v), then measure acidity or alkalinity using a calibrated pH meter. |
| Sulfated Ash (Residue on Ignition) | Residue on Ignition Method | Ignite the sample at high temperature and weigh the remaining inorganic residue to evaluate inorganic impurity content. |
| Chloride Content | Ion Chromatography or Argentometric Method | Ion chromatography accurately measures free chloride ions; argentometric method uses silver nitrate titration, suitable for rapid detection of total chlorides. |
| Sulfonic Acid Group Confirmation | Fourier Transform Infrared Spectroscopy (FTIR) | Confirm functional groups via characteristic absorption peaks, such as S=O stretching vibrations at ~1030 cm⁻¹ and ~1170 cm⁻¹, and N–H bending near 1600 cm⁻¹. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Use ¹H-NMR and ¹³C-NMR to confirm molecular structure, especially substitution patterns and hydrogen/carbon environments. |
