Manufacturing Quality Control of 1-BROMO-3,5-DIIODOBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., mono-iodo, tri-iodo, debromo, or hydrolysis products) via gradient HPLC-UV against qualified reference standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, methanol, DMF) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity and isotopic resolution. |
| Halogen Content (Total Iodine/Bromine) | Oxygen Flask Combustion + Ion Chromatography | Combustion in oxygen flask converts halogens to halide ions, followed by separation and quantification via ion chromatography with conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against established visual reference standards. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Measurement of mass loss after drying under controlled temperature and vacuum, indicating volatile or hygroscopic components. |
| Residue on Ignition | Gravimetric (500–600 C) | Quantification of non-volatile inorganic residue after high-temperature ashing of the sample in a platinum crucible. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed dry or wet samples. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined aqueous suspension (e.g., 1% w/v in water) using calibrated pH electrode per USP <791>. |
