Industrial Applications of Potassium 3-(phenylsulfonyl)benzenesulfonate
| Industry | Application | Process |
|---|---|---|
| Dye Industry | Azo dye intermediate | Used in the synthesis of benzothiazole- and heterocyclic azo dyes; sulfonamide functionality is introduced via diazotization-coupling reactions |
| Pharmaceutical Industry | Pharmaceutical synthesis intermediate | Employed to construct biologically active molecules containing sulfonamide groups, such as side-chain modifications in anti-inflammatory agents or protein kinase inhibitors |
| Pesticide Industry | Agrochemical intermediate | Applied as a phenyl ring substituent precursor in the synthesis of sulfonylurea herbicides; target compounds are prepared through chlorination, amination, and related steps |
Manufacturing Quality Control of Potassium 3-(phenylsulfonyl)benzenesulfonate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Physical Characteristics | Visual Inspection and Physical Description | The sample appears as a white or off-white crystalline powder, free of visible impurities and odor, meeting the appearance requirements specified in pharmacopoeia or company standards. |
| Content (Main Component Purity) | High-Performance Liquid Chromatography (HPLC) | Using a C18 column with gradient elution of water-methanol or acetonitrile, detected by UV detector at 254 nm. The external standard method is used to calculate the main component content, typically requiring ≥98.0%. |
| Moisture Content | Karl Fischer Titration Method | Determined using either volumetric or coulometric Karl Fischer titration to measure residual moisture. Moisture content is controlled at ≤1.0% to ensure product stability and shelf life. |
| Sulfate Impurities (SO₄²⁻) | Sulfate Barium Turbidimetry | After acidification, barium chloride is added to form barium sulfate precipitate. The turbidity is compared with a standard solution, with sulfate impurity limit controlled (e.g., ≤0.05%). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After ashing or digestion, lead, cadmium, mercury, arsenic, and other heavy metals are measured. Results comply with ICH Q3D or pharmacopoeial limits (e.g., ≤10 ppm). |
| Residual Solvents | Gas Chromatography (GC) | Using headspace or direct injection, separation is performed on polar columns such as DB-624 to detect residual solvents like ethanol, acetone, DMF. Levels are controlled according to ICH Q3C guidelines. |
| pH Value | pH Meter Determination | Sample is prepared as a 1% aqueous solution and pH measured at 25°C using a calibrated pH meter. pH range is controlled (e.g., 5.0–7.5), reflecting acid-base stability. |
| Chloride Impurities | Silver Nitrate Titration or Ion Chromatography | After acidification with nitric acid, silver nitrate is added to form silver chloride precipitate. Turbidity comparison or ion chromatography is used for quantification, with Cl⁻ content controlled ≤0.05%. |
| Ash Content (Sulfated Ash) | Closed Combustion Residue Test | Sample is incinerated at 500–600°C until constant weight. The residue mass is weighed and controlled at ≤0.1%, indicating inorganic impurity levels. |
| Microbial Limits (if applicable) | Microbial Counting Method (USP/EP) | If used as a pharmaceutical intermediate, tests for total aerobic bacteria count, mold and yeast, and Escherichia coli are performed, complying with pharmacopoeial limits for non-sterile preparations. |
| Particle Size Distribution (if applicable) | Laser Diffraction or Sieving | For powder process control, D10, D50, and D90 particle size distributions are measured to ensure consistent flowability and solubility. |
