Manufacturing Quality Control of 4-BroMo-6-chloropyridazin-3(2H)-one
| 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-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., acetone, methanol, DMF) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; measures water by stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other toxic metals after acid digestion, using isotopic detection for high sensitivity and specificity. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue after controlled ashing at 600-750 C; measures inorganic non-volatile impurities. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference samples. |
| Particle Size Distribution | Laser Diffraction | Measurement of size distribution in dry or wet dispersion using Mie scattering theory and optical detection of diffracted laser light. |
| Bulk Density | Tap Density Tester | Determination of mass per unit volume after standardized tapping; follows ASTM D1895 Method A. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 10% w/v in water) using calibrated glass electrode after equilibration. |
