Manufacturing Quality Control of 4,4'-DICHLORODIPHENYL DISULFIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by retention time and peak area comparison against a certified reference standard using UV detection. |
| Related Substances | HPLC-UV | Separation and detection of impurities based on relative retention times and UV response; identified and quantified against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Volatile organic solvents are separated by gas chromatography and detected via flame ionization; quantified using calibration curves. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion; metals quantified by atomic emission intensity at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint determined by potential change due to AgCl precipitation. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; determined by controlled heating and visual or automated detection. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria under standardized lighting conditions. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Sulfur Content | Combustion IC | Oxidative combustion followed by ion chromatographic detection of sulfate ions in the absorption solution. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to determine size distribution based on Mie theory. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume measured by gently pouring sample into a calibrated cylinder and recording settled volume. |
