Manufacturing Quality Control of 3-Bromo-2-cyanopyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances (Impurities) | HPLC-UV or UPLC-MS | Separation and detection of structurally related impurities (e.g., 3-bromo-2-hydroxypyridine, unreacted 2-cyanopyridine) via retention time and spectral matching. |
| Residual Solvents (e.g., Acetonitrile, DMF) | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion, based on mass-to-charge ratio detection with isotopic resolution and ultra-trace sensitivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (700–800 °C) and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary method per USP <741>. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation and quantification of chloride ions after sample dissolution and filtration, based on anion exchange and conductivity response. |
| Appearance & Color | Visual Inspection / Hazen/APHA Color Scale | Subjective assessment of physical state (crystalline solid) and color intensity compared to platinum-cobalt standards. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder using a calibrated graduated cylinder. |
| Particle Size Distribution | Laser Diffraction (Dry Dispersion) | Analysis of particle size distribution based on angular scattering pattern of laser light through dispersed powder. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line (589 nm) to detect chiral impurities or enantiomeric excess (though compound is achiral, used for identity confirmation). |
