Manufacturing Quality Control of 2,4-Dibromonitrobenzene
| 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., monobromo, tribromo, nitrophenol derivatives) using gradient HPLC-UV against reference standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., dichloromethane, toluene) based on retention time and calibration curves. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, based on atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified using external calibration. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-750 C followed by sulfuric acid treatment and final weighing of residual inorganic ash. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference samples. |
| Particle Size Distribution | Laser Diffraction | Measurement of size distribution in dry powder mode using Mie scattering theory and validated optical model. |
| Bulk Density | Tap Density Tester | Determination of mass per unit volume after standardized tapping (ASTM D1895 Method A). |
| Organic Volatile Impurities (OVI) | GC-MS | Identification and quantification of unknown volatile impurities using gas chromatography coupled with mass spectrometry and library matching. |
