Manufacturing Quality Control of 1,3-dibroMo-2-iodobenzene
| 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 to a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode-array detection, with spectral comparison and relative response factor correction. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine/methanol medium; water reacts stoichiometrically with iodine and sulfur dioxide. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion; emission intensity at characteristic wavelengths correlates with metal concentration. |
| Residue on Ignition | Gravimetric Analysis | Mass difference measured before and after high-temperature ashing (700-800 C) to determine inorganic residue content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or via automated detection as solid transforms to liquid under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator; measures free acidic impurities neutralizable by base. |
| Iodine Content | Iodometric Titration | Oxidation of iodide to iodine by added oxidant, followed by titration with standardized sodium thiosulfate solution using starch indicator. |
| Bromine Content | Oxygen Flask Combustion + Potentiometric Titration | Combustion in oxygen flask converts organobromine to bromide, followed by titration with silver nitrate using potentiometric endpoint detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution according to Mie theory. |
