Manufacturing Quality Control of 2-Thienyl disulfide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities based on retention time and UV spectral match; quantified relative to main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., dichloromethane, toluene) per ICH Q3C. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification after acid digestion; provides detection below 1 ppb for Pb, Cd, Hg, As, etc. |
| Sulfur Content | Combustion IC | Oxidative combustion followed by ion chromatographic detection of sulfate ions; accurate for organosulfur compounds. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating rate (ASTM D1565). |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against standard reference under controlled lighting. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions in aqueous extract using suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Mass determination of inorganic residue after high-temperature ashing (700–800 C) per USP <281>. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after standardized tapping (ASTM D1895 Type A). |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate size distribution based on Mie theory (ISO 13320). |
