Manufacturing Quality Control of Bis(2-nitrophenyl) disulfide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-nitro analogs, disulfide isomers, nitrophenol derivatives) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., toluene, ethyl acetate, methanol) per ICH Q3C. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, per USP <232> and <233>. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; detects residual hydrochloric acid or chlorinated by-products. |
| Sulfur Content | Combustion IC | High-temperature combustion followed by ion chromatographic detection of sulfate, used to verify stoichiometry and detect sulfur-containing impurities. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water content per USP <921>. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus; verifies crystallinity and identity. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and against standard reference. |
| Organic Volatile Impurities (OVI) | GC-FID | Targeted GC-FID analysis for low-boiling impurities (e.g., nitrobenzene, aniline, benzene) using specified method parameters. |
| Residue on Ignition | Gravimetric Analysis | Weight loss on ignition at 600 C to determine inorganic ash content, indicating inorganic salt contaminants. |
| Particle Size Distribution | Laser Diffraction | Dry dispersion laser diffraction to measure D10, D50, D90 values, relevant for downstream processing consistency. |
