Manufacturing Quality Control of SODIUM P-TOLUENESULFONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NaTos) | Acid-base titration | Quantifies NaTos by back-titration after hydrolysis to p-toluenesulfonic acid and neutralization with standardized NaOH. |
| Moisture content | Karl Fischer titration | Measures water content via coulometric or volumetric reaction between water and iodine in a methanol-based reagent. |
| pH of 5% aqueous solution | pH potentiometry | Determines hydrogen ion activity using calibrated glass electrode in a standardized aqueous solution. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Quantifies total heavy metals by atomizing the sample and measuring absorbance at characteristic wavelengths. |
| Sulfate (SO4) | Gravimetric analysis | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after ignition. |
| Chloride (Cl) | Potentiometric titration with AgNO3 | Measures chloride via argentometric titration using silver nitrate and a silver indicator electrode. |
| Iron (Fe) | ICP-OES | Quantifies iron by plasma excitation and detection of element-specific emission lines. |
| Loss on drying (LOD) | Thermogravimetry | Determines volatile content by measuring mass loss after heating at 105 C for 2 hours. |
| Appearance | Visual inspection | Evaluates physical state, color, and presence of foreign particles against standard reference samples. |
| Solubility in water | Qualitative solubility test | Confirms complete dissolution of specified amount in distilled water at 25 C with no residue. |
| Residue on ignition | Gravimetric analysis | Measures inorganic ash content after incineration at 600 C to constant weight. |
| Organic impurities (related substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection at 254 nm. |
