Industrial Applications of 2,5-DIFLUOROBENZENESULFONYL CHLORIDE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Pharmaceutical Intermediate | Used as a fluorinated benzenesulfonylation reagent to synthesize sulfonamide- or sulfonylurea-based active pharmaceutical ingredients, introducing the 2,5-difluorobenzenesulfonyl group to enhance metabolic stability or biological activity. |
| Agrochemicals | Agrochemical Intermediate | Used to synthesize fluorinated benzenesulfonylurea herbicides or other sulfonamide-based insecticides and fungicides, leveraging its electron-withdrawing group to improve efficacy. |
| Organic Synthesis | Introduction of Protecting Groups for Alcohols and Amines | Applied as a sulfonylation reagent in multistep organic synthesis to react with alcohols or amines, forming corresponding sulfonate esters or sulfonamides for hydroxyl or amino group protection. |
| Dyes and Pigments | Fluorinated Dye Intermediate | Used to synthesize fluorinated azo dyes or fluorescent dyes; introduction of the sulfonyl chloride group improves color fastness, solubility, or hue properties. |
| Electronic Chemicals | Synthesis of Organic Optoelectronic Materials | Applied in synthesizing electron-transport or hole-blocking materials for organic light-emitting diodes (OLEDs) and organic photovoltaics, where the fluorinated structure facilitates energy-level tuning. |
Manufacturing Quality Control of 2,5-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 a certified reference standard using a non-polar capillary column. |
| 2,5-Difluorobenzenesulfonyl Chloride Identity | Fourier Transform Infrared Spectroscopy (FT-IR) | Confirmation via characteristic absorption bands, especially S=O stretch (~1370 cm-1) and C-F stretch (~1100 cm-1). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detection and quantification of volatile organic solvents (e.g., dichloromethane, toluene) using headspace sampling and GC-FID. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol-based reagent. |
| Acid Value | Acid-Base Titration (NaOH in isopropanol/water) | Neutralization of acidic impurities (e.g., hydrolyzed sulfonyl chloride) with standardized NaOH solution using phenolphthalein indicator. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Separation of Cl- anions on an anion-exchange column followed by quantitative detection via suppressed conductivity. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Multi-element detection after microwave-assisted acid digestion, based on elemental mass-to-charge ratios. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of sample under controlled temperature and vacuum, followed by weighing of residual solids. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement (APHA scale) | Comparison of sample solution color intensity against platinum-cobalt standards at 455 nm wavelength. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary tube method per USP <741>. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitation of sulfate as BaSO4 in acidic medium, followed by filtration, drying, and weighing. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase C18 column; detection at 220 nm and 254 nm to identify and quantify structurally related compounds. |
