Manufacturing Quality Control of 3-BROMO-4-NITROPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., starting materials, intermediates, degradation products) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., methanol, dichloromethane, toluene) per ICH Q3C. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content in the sample. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, with detection at sub-ppt levels. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light to confirm chiral integrity and absence of racemization. |
| Residue on Ignition | Gravimetric Analysis | Weighing of inorganic residue after ignition at 600 C, reflecting total inorganic impurities. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) to detect acidic/basic degradation products. |
