Manufacturing Quality Control of 4-bromo-5-methyl-2-nitroaniline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC-UV; identification by retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., methanol, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion by optical emission spectroscopy at characteristic wavelengths. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on anion-exchange column with carbonate eluent. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled combustion of sample with sulfuric acid followed by high-temperature ashing and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against defined reference standards. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample suspension. |
| Bulk Density | USP <616> Tap Density Test | Determines mass per unit volume of powder after standardized tapping; reports both untapped and tapped density. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode pH meter. |
