| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Synthesis of pharmaceutical intermediates | Used in the preparation of sulfonamide compounds |
| Agrochemical Industry | Preparation of fluorinated agrochemical intermediates | Combined fluorination and sulfonylation reactions |
| Chemical Research | Laboratory reagent | Applied in fluorination and sulfonylation steps of organic synthesis |
| Materials Science | Functional polymer modifier | Introduces sulfonyl fluoride groups to enhance material properties |
| 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. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities are vaporized in sealed vials and quantified by GC-FID or GC-MS relative to calibration standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine is generated coulometrically to react stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration (NaOH in methanol) | Neutralization of acidic impurities (e.g., sulfonic acids) with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Heavy Metals (as Pb) | ICP-OES after acid digestion | Sample digested in nitric/hydrochloric acid; metals quantified by plasma emission intensity at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection via suppressed conductivity. |
| Sulfate Impurity | Ion Chromatography (IC) with conductivity detection | Same principle as chloride, optimized for sulfate retention and detection under alkaline eluent conditions. |
| Residual Fluoride | Ion-Selective Electrode (ISE) potentiometry | Fluoride activity measured via potential difference between fluoride-selective electrode and reference electrode in buffered solution. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection (against white/black background) | Assessment of physical state, color, and presence of particulates or phase separation in solid form. |
| Loss on Drying (LOD) | Gravimetric Analysis (105 C, 2 h) | Mass loss upon controlled heating determined by pre- and post-drying weight difference under specified conditions. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and UV absorbance at 254 nm. |
