Manufacturing Quality Control of 4-BROMO-2-CHLOROBENZENESULFONAMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., isomers, dehalogenated by-products) using gradient HPLC and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous medium. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Potentiometric Titration | Measures chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode based on precipitation endpoint. |
| Sulfonamide Group Integrity | FTIR Spectroscopy | Confirms presence of S=O and S-N bonds via characteristic absorption bands in mid-infrared region (1350–1150 cm-1). |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and absence of significant eutectic impurities. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against defined standards. |
| Bulk Density | ASTM D1895 | Measures mass per unit volume of freely settled powder using standardized graduated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder using Mie scattering theory applied to laser light diffraction pattern. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing. |
