Manufacturing Quality Control of 4-Bromobenzenesulfonamide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by gradient HPLC-UV against qualified reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, toluene) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; measures water via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion, using plasma excitation and emission spectroscopy at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on anion-exchange column with conductivity detection; chloride quantified against calibration standards. |
| Sulfate Impurity | Ion Chromatography | Same principle as chloride, optimized for sulfate elution and detection using suppressed conductivity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or optically as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white light and against reference standards. |
| Bulk Density | USP <616> Tap Density Method | Mass per unit volume measured after controlled tapping of a graduated cylinder containing the sample. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volume-based particle size distribution. |
| Residue on Ignition | Gravimetric Analysis | Mass loss upon high-temperature ashing (700-800 C) followed by weighing of non-volatile residue. |
