Manufacturing Quality Control of S,S-dimethyl sulfoximine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies DMSO-dimethyl sulfonium imide by retention time and peak area against calibrated standards. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Heavy Metals | ICP-OES | Quantifies total heavy metals (e.g., Pb, Cd, Hg, As) by atomic emission intensity after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate ions using anion exchange and suppressed conductivity detection. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Evaluates yellowness by comparing sample color to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at 20 degC using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at 20 degC to infer purity and concentration. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling organic impurities by GC analysis of vapor phase above heated sample. |
| Residual Solvents | Gas Chromatography (GC) with FID or MS detection | Identifies and quantifies common solvents (e.g., acetone, methanol, DMF) using internal standard calibration. |
