Manufacturing Quality Control of 2,4-DIFLUOROBENZENESULFONYL CHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard using a non-polar capillary column. |
| 2,4-Difluorobenzenesulfonyl Chloride Identity | Fourier Transform Infrared Spectroscopy (FTIR) | Confirmation via characteristic absorption bands corresponding to S=O, S-Cl, and aromatic C-F bonds. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detection and quantification of volatile organic solvents (e.g., dichloromethane, toluene) by equilibrium partitioning into headspace. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in anhydrous methanol-based medium. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., HCl, sulfonic acids) using phenolphthalein indicator or potentiometric endpoint detection. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample solution color intensity against platinum-cobalt standards measured at 455 nm. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Separation of Cl- on anion-exchange column followed by suppressed conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in argon plasma; quantification via element-specific emission wavelengths. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of volatile components at 105 C followed by weighing of residual solids. |
| Sulfate Impurity | Barium Sulfate Turbidimetry | Precipitation of sulfate as BaSO4 in acidic medium; quantification via light scattering measurement. |
| Related Substances (Impurity Profile) | High Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column; detection at 220 nm and 254 nm for structurally related degradants and synthesis intermediates. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density at 20 C based on resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
