Manufacturing Quality Control of BENZENETHIONOSULFONIC ACID, SODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NaC6H5SO2S) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl after acid hydrolysis to liberate sulfuric acid. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in a methanol-based reagent. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of a standardized solution using calibrated pH electrode. |
| Heavy Metals (as Pb) | ICP-OES | Simultaneously quantifies trace heavy metals after acid digestion using plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Potentiometric Titration | Measures chloride ions by titration with silver nitrate using silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Residue on Ignition | Weight Loss on Ignition | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection at 254 nm. |
| Iron (Fe) | AAS | Quantifies iron content by atomic absorption measurement of ground sample digestate at characteristic wavelength. |
| Sodium Content | Flame Photometry | Measures sodium ion concentration based on intensity of emitted light at 589 nm in flame excitation. |
| Appearance (Color and Clarity) | Visual Inspection | Assesses physical state, color (white to off-white), and clarity against standard reference in aqueous solution. |
| Solubility in Water | Qualitative Solubility Test | Confirms complete dissolution in specified volume of water at defined temperature without residue or turbidity. |
