Manufacturing Quality Control of 2,6-DICHLOROBENZENESULFONYL 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 | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities are equilibrated in headspace vial and quantified by GC-FID or GC-MS against calibration standards. |
| Moisture Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated coulometrically to react stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities (e.g., residual sulfonic acids) with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Chloride Content (Inorganic) | Ion Chromatography (IC) with conductivity detection | Separation and quantification of chloride anions on an anion-exchange column followed by suppressed conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection after acid digestion; isotopic quantification at trace levels using mass spectrometric separation. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or via automated optical detection as solid transforms to liquid under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and against white/black background. |
| Organic Impurities (Related Substances) | HPLC with UV detection | Separation on reversed-phase C18 column and detection at 254 nm; identification and quantification relative to main peak using reference standards. |
| Sulfur Content | High-Temperature Combustion followed by IR Detection | Complete oxidation of sulfur to SO2, followed by infrared absorption measurement proportional to sulfur concentration. |
| Particle Size Distribution | Laser Diffraction | Analysis of angular scattering pattern of laser beam passed through dispersed sample to calculate size distribution based on Mie theory. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Mass per unit volume measured after specified tapping steps in a calibrated cylinder to assess flow and packing behavior. |
