Manufacturing Quality Control of 4-BROMO-N,N-DIETHYLBENZENESULPHONAMIDE
| 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-DAD | Separation and identification of impurities using HPLC coupled with diode-array detection; impurities quantified relative to main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and peak area. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to measure water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element analysis after acid digestion; detection based on characteristic atomic emission spectra in inductively coupled plasma. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection for quantitative chloride measurement. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as solid transforms to liquid; measured per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard references under controlled lighting conditions. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing to determine inorganic non-volatile impurities. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after standardized tapping; used for flow and handling assessment. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine size distribution of dry or dispersed particles. |
| Sulfonamide Content | Acid-Base Titration | Back-titration of excess standardized NaOH after alkaline hydrolysis; sulfonamide group quantified via consumed acid. |
