Manufacturing Quality Control of 2-Methyl-2-thiopseudourea sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (S-Methylisothiourea Sulfate) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH after alkaline hydrolysis and back-titration. |
| Water Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in a methanol-based reagent. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after ignition and drying. |
| Chloride Impurity | Argentometric Titration | Titrates chloride ions with standardized silver nitrate using potassium chromate indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by weighing residue after high-temperature ashing at 700-800 C. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile matter by weight loss after drying at 105 C for 2 hours under controlled conditions. |
| Iron (Fe) Content | ICP-OES | Quantifies iron after sample digestion by measuring emitted light intensity at Fe-specific wavelengths in plasma. |
| Appearance (Color and Clarity) | Visual Inspection | Assesses physical state, color, and clarity against standard references in aqueous solution (1% w/v). |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral purity and identity (though compound is achiral, detects chiral contaminants). |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents and volatile organics using flame ionization detection. |
