Manufacturing Quality Control of 2,4-Dibromobenzonitrile
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities by retention time and UV absorbance relative to the main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvent residues are vaporized in sealed vials and analyzed by GC-FID or GC-MS. |
| Moisture Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection after acid digestion; emission intensity at characteristic wavelengths correlates with metal concentration. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection via electrical conductivity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the solid phase changes to liquid under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Ash Content | Gravimetric Analysis (Muffle Furnace) | Residue weight after incineration at 550-600 C, representing inorganic non-volatile impurities. |
| Particle Size Distribution | Laser Diffraction Particle Size Analyzer | Analysis of light scattering patterns from dispersed particles to determine size distribution by volume. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Mass per unit volume measured by pouring sample into a calibrated cylinder and tapping to standardize packing. |
