Manufacturing Quality Control of 3-BROMO-2-METHYL-5-NITROPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities using gradient HPLC-UV; identification and reporting per ICH Q3B thresholds. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., DMF, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Measures total heavy metal content (Pb, Cd, Hg, As, etc.) after acid digestion by optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral impurities or enantiomeric excess using sodium D-line (589 nm). |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of freely settled and tapped powder sample using standardized mechanical tapping procedure. |
