Manufacturing Quality Control of P-TOLYL DISULFIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via iodine-sulfur dioxide redox reaction in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metals (e.g., Pb, Cd, Hg) by atomic absorption of specific wavelengths. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration using silver indicator electrode. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid under controlled heating. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration. |
| Solubility in Common Solvents | Qualitative Solubility Test | Evaluates dissolution behavior in specified solvents (e.g., ethanol, toluene) at room temperature. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Identifies and quantifies low-boiling contaminants using equilibrium vapor phase analysis. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Measures size distribution of solid particles in suspension via light scattering pattern analysis. |
