Manufacturing Quality Control of 3,4-Dichloroaniline-6-sulfonic acid
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Inspect the sample by eye for color, physical state (e.g., whether it is white to off-white crystalline powder), and presence of foreign particles to determine compliance with quality specifications. |
| Identification | Infrared Spectroscopy (IR) High-Performance Liquid Chromatography (HPLC) |
- Infrared Spectroscopy (IR): Record the infrared absorption spectrum of the sample and compare it with a reference spectrum to confirm the presence of characteristic functional groups (e.g., —NH₂, —SO₃H, aromatic rings, C–Cl bonds). - HPLC Retention Time Comparison: Under identical chromatographic conditions, the retention time of the main peak of the sample should match that of the reference standard. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with methanol-water or acetonitrile-buffer solution as the mobile phase. Detect using a UV detector (typically at 240–280 nm). Calculate the content of 3,4-dichloroaniline-6-sulfonic acid using external standard method or area normalization method. Purity is typically required to be ≥98.0%. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Under the same or optimized chromatographic conditions used for assay, separate and detect possible organic impurities (e.g., unreacted starting materials, by-products, degradation products). Use area normalization method or main component self-reference method with correction factors to control limits for individual and total impurities. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at 105°C to constant weight and measure the percentage weight loss. Used to control moisture and volatile substances; typically limited to ≤1.0%. |
| Sulfated Ash / Residue on Ignition | High-Temperature Ashing Method | Ignite the sample at high temperature (approximately 700–800°C), then weigh the residual inorganic matter. Used to control inorganic impurities (e.g., metal salts, catalyst residues); typically limited to ≤0.1%. |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v) and measure pH using a calibrated pH meter. Due to the sulfonic acid group, the solution is typically acidic with a pH of approximately 2–4. |
| Chloride Content | Ion Chromatography (IC) or Silver Nitrate Titration | - Ion Chromatography (IC): Accurately determine the content of free chloride ions. - Silver Nitrate Titration: Suitable for rough estimation of higher chloride levels by quantifying AgCl precipitate formation. Used to control residual inorganic chlorides from the synthesis process. |
