Manufacturing Quality Control of 2,5-DICHLOROBENZENESULFONYL 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 against a certified reference standard. |
| Residual Solvents (e.g., DCM, toluene) | GC-FID | Separation and quantification of volatile organic solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent, measuring endpoint coulometrically or volumetrically. |
| Acid Value | Acid-Base Titration | Neutralization of acidic functional groups (–SO₂Cl) with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion via inductively coupled plasma mass spectrometry with isotope dilution for high sensitivity and accuracy. |
| Chloride Ion Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride anions using anion-exchange column and suppressed conductivity detector. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid phase transition using calibrated capillary apparatus per USP <741>. |
| Appearance & Color | Visual Inspection / APHA Color Scale | Subjective assessment of physical state and color intensity compared to platinum-cobalt standard solutions. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue after controlled high-temperature ashing (500–600 °C) in a platinum crucible. |
| Organic Volatile Impurities (e.g., benzyl chloride, dichlorobenzene) | GC-MS | Identification and quantification of structurally related volatile impurities using gas chromatography coupled with mass spectrometric detection. |
| Sulfur Content | Combustion IC | Oxidative combustion followed by ion chromatographic quantification of sulfate ions derived from total sulfur. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via light scattering pattern to determine volume-based particle size distribution (D10, D50, D90). |
