Manufacturing Quality Control of 2-Aminobenzenesulfonamide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and UV spectra support structural assignment. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated response factors. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities at characteristic wavelengths in inductively coupled plasma. |
| Sulfate Residue | Ion Chromatography | Separation of sulfate anions on an anion-exchange column with suppressed conductivity detection using sodium carbonate/bicarbonate eluent. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using a silver/silver chloride electrode; endpoint detected by potential inflection due to AgCl precipitation. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of pH in a defined saturated aqueous suspension using a calibrated glass electrode pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the solid transforms to liquid under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against a white background under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dispersed dry or wet samples. |
| Loss on Drying | Gravimetric Method | Weight loss measured after drying a sample at specified temperature and time under vacuum or forced-air conditions. |
