Manufacturing Quality Control of alpha-Bromo-p-toluenesulphonyl chloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., 4-bromobenzenesulfonyl chloride, 4-methylbenzenesulfonyl chloride) using gradient HPLC-UV. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine water content based on stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring inorganic residue as percentage of initial mass. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode to detect endpoint via potential change from AgCl precipitation. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Determination | Observation of solid-to-liquid phase transition temperature range using calibrated capillary apparatus. |
| Organic Volatile Impurities | GC-FID | Detection and quantification of residual solvents (e.g., dichloromethane, toluene) by gas chromatography with flame ionization detection. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered laser light intensity to calculate volume-based particle size distribution in dry dispersion mode. |
| Bulk Density | Graduated Cylinder Method | Mass of material freely poured into a calibrated cylinder divided by its settled volume. |
| Sulfate Content | Gravimetric Sulfate Precipitation | Precipitation as BaSO4 after digestion and oxidation, followed by filtration, drying, and weighing. |
