Manufacturing Quality Control of 4-Chlorobenzenesulfonamide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., 4-chlorobenzenesulfonyl chloride, aniline derivatives) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., toluene, methanol, ethyl acetate) by gas chromatography with flame ionization detection against calibrated standards. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensity at element-specific wavelengths. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric determination of water content via stoichiometric iodine reaction with water in anhydrous methanol-based medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Chloride Ion Impurity | Ion Chromatography (IC) | Separation and quantification of free chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfonamide Functional Group Confirmation | FT-IR Spectroscopy | Verification of characteristic vibrational bands (e.g., S=O asymmetric/symmetric stretch ~1350 & 1150 cm⁻¹, N–H stretch ~3300 cm⁻¹). |
