Manufacturing Quality Control of 2,2'-Dithiobisbenzanilide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C in a platinum crucible and weighing the non-volatile residue after cooling in a desiccator. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Reaction with hydrogen sulfide under controlled pH to form colored metal sulfides, compared visually or spectrophotometrically against lead standard. |
| Chloride Impurity | Potentiometric Titration with Silver Nitrate | Titration using AgNO3 solution with silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Sulfur Content | Combustion IC | High-temperature combustion followed by ion chromatographic separation and conductivity detection of sulfate ions. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination using capillary tube method per USP <741>, observing temperature range of solid-to-liquid phase transition. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents via gas chromatography with flame ionization detection using internal standard calibration. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities using diode array detection for spectral confirmation and peak purity assessment. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Atomization of acid-digested sample in air-acetylene flame and measurement of absorbance at 248.3 nm. |
| Bulk Density | Graduated Cylinder Method | Mass of freely poured sample divided by its volume in a calibrated cylinder, measured per ASTM D1895. |
