Manufacturing Quality Control of 3,5-DIBROMO-4-METHOXYPYRIDINE-N-OXIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV/DAD | Separation and identification of impurities (e.g., mono-bromo, debromo, or hydrolysis by-products) via gradient HPLC with diode-array detection and relative response factor correction. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., methanol, dichloromethane, toluene) based on calibrated external standards. |
| Heavy Metals (Total) | ICP-MS | Digestion followed by quantification of Pb, Cd, Hg, As, and other regulated metals using inductively coupled plasma mass spectrometry for sub-pptr sensitivity. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration using iodine generated in situ to determine trace water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Ignition of sample at 700–800 °C followed by weighing of non-volatile inorganic residue to assess inorganic ash content. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection, calibrated against NaCl standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary apparatus per USP <741>. |
