Manufacturing Quality Control of N,N'-Di-(4-methyl-phenyl)-benzidine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against certified reference standard. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., toluene, xylene) by gas chromatography with flame ionization detection using calibrated external standards. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-MS | Measures trace heavy metal concentrations after acid digestion by inductively coupled plasma mass spectrometry with isotope-dilution quantification. |
| Chloride Ion | Ion Chromatography | Separates and detects chloride anions in aqueous extract using suppressed conductivity detection with carbonate/bicarbonate eluent. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue mass after high-temperature incineration (550-600 C) followed by cooling and precise weighing. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating ramp. |
| Organic Impurities (Related Substances) | HPLC-DAD | Identifies and quantifies structurally related impurities (e.g., monoalkylated, oxidized, or hydrolyzed derivatives) via HPLC with diode array detection. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder using a standardized graduated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder by analyzing angular scattering pattern of laser beam passed through dispersed sample. |
| pH of Aqueous Slurry | Potentiometric pH Measurement | Determines acidity/basicity of 10% w/w aqueous suspension using calibrated glass electrode and pH meter. |
| Sulfated Ash | Gravimetric Analysis | Quantifies non-volatile sulfate-containing residues after ignition with sulfuric acid pretreatment and subsequent high-temperature ashing. |
