Manufacturing Quality Control of 1,4-DIBROMOBENZENE-D4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID or HPLC-UV | Quantitative separation and detection based on retention time and peak area relative to a certified reference standard. |
| Deuterium Incorporation Ratio | 1H NMR Spectroscopy | Measures the reduction in aromatic proton signal intensity at positions 1 and 4 relative to non-deuterated analogs. |
| Residual Solvents | Headspace GC-FID | Volatile solvents are vaporized in sealed vials and quantified by gas chromatographic separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to oxidize water, with endpoint detected amperometrically. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection via atomic emission from plasma-excited atoms following acid digestion of the sample. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of anions on an ion-exchange column with conductivity detection using suppressed eluent. |
| Residual Palladium | ICP-MS | Ultra-trace metal quantification by mass spectrometric detection of elemental ions after microwave-assisted digestion. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of particulates or phase separation against defined standards. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after controlled heating under vacuum or nitrogen to remove volatile components. |
| Acid-Base Impurities | Non-aqueous Titration | Titration with perchloric acid in glacial acetic acid using potentiometric or indicator endpoint detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering patterns from dispersed particles to calculate size distribution by Mie theory. |
