Manufacturing Quality Control of DIBENZYL SULFOXIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities via absorption of characteristic wavelength light by ground-state atoms in a flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfate Impurity | Barium Chloride Precipitation / Turbidimetry | Formation of insoluble barium sulfate precipitate; concentration determined by light scattering measurement. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against a white background under controlled lighting. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed as the temperature range over which solid transforms to liquid in a calibrated capillary apparatus. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral impurities or enantiomeric excess in solution. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic solvents quantified via equilibrium vapor phase analysis using GC-FID or GC-MS. |
| Iron Content | ICP-OES | Multi-element detection based on intensity of element-specific atomic emission lines following plasma atomization and excitation. |
