Manufacturing Quality Control of 4-Bromo-1,2-benzenediamine
| 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. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., 4-bromoaniline, benzidine derivatives) via gradient HPLC-UV, using relative response factors or external standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, toluene, DMF) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, offering sub-pptr detection limits and compliance with ICH Q3D. |
| Moisture Content | Karl Fischer Titration | Coulometric or volumetric titration measuring water content based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus; deviation from literature value (109–111 °C) indicates purity issues. |
| Chloride Impurity | Ion Chromatography (IC) | Quantification of chloride ions via suppressed conductivity detection after separation on an anion-exchange column. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (700–800 °C) and weighing of residual residue. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using a calibrated pH electrode to detect acidic/basic degradation products. |
| Specific Optical Rotation | Polarimetry | Determination of chiral purity (if applicable) and identity verification using sodium D-line light; racemic material should yield near-zero rotation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine D10, D50, D90 values, ensuring consistency for downstream processing (e.g., formulation). |
