Manufacturing Quality Control of 4,5-DIBROMO-2-PHENYL-2,3-DIHYDROPYRIDAZIN-3-ONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification by retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., dichloromethane, toluene) via headspace GC with flame ionization detection using calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Quantifies toxic elements (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution for high sensitivity. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion-exchange column separation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after charring at 700-800 C and weighing the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and against reference samples. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely settled powder using calibrated cylinder and analytical balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in laser light scattering from dispersed particles in air or liquid medium. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light through a solution in specified solvent and path length to confirm chiral integrity. |
