Manufacturing Quality Control of N-(2-Hydroxypropyl)benzenesulphonamide
| 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 against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water via electrochemical or stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Sulfate Residue | Ion Chromatography | Separation and conductivity detection of sulfate anion after sample dissolution and filtration; quantified against sulfate standard. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential jump due to AgCl precipitation. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range where solid transforms to liquid under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against specified criteria (e.g., white to off-white crystalline powder). |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under specified temperature and vacuum conditions, reflecting volatile content including residual solvents and moisture. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess acidic/basic degradation products. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through solution, indicating chiral purity and absence of racemization. |
