Manufacturing Quality Control of 2-Bromobenzenesulphonyl chloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separation and quantification of volatile organic solvents by equilibrium partitioning into headspace gas followed by GC analysis. |
| Moisture Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., residual HCl or sulfonic acids) using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification via ionization in plasma and mass-selective detection with high sensitivity and low detection limits. |
| Chloride Ion (Cl-) | Ion Chromatography (IC) | Separation of anions on an ion-exchange column followed by conductivity detection after chemical suppression. |
| Sulfate Ion (SO42-) | Ion Chromatography (IC) | Anion separation and quantification using suppressed conductivity detection after eluent optimization for sulfate resolution. |
| 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 against specified criteria under controlled lighting conditions. |
| Organic Impurities (Related Substances) | HPLC with UV detection | Separation of structurally related compounds on a reversed-phase column and quantification using UV absorbance at 254 nm. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature ashing and cooling in a desiccator. |
| Bulk Density | Tap Density Measurement | Determination of mass per unit volume after standardized mechanical tapping of a powder sample in a calibrated cylinder. |
