Manufacturing Quality Control of 4-Bromo-3-chloropyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reverse-phase C18 column and UV absorbance at 254 nm. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile organic solvents are extracted into headspace and quantified by GC-FID using calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol-based reagent. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Multi-element detection after acid digestion and nebulization; provides sub-ppt detection limits. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation and quantification of chloride ions on anion-exchange column followed by conductivity measurement. |
| Bromide Content | Ion Chromatography (IC) with conductivity detection | Separation and quantification of bromide ions on anion-exchange column followed by conductivity measurement. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or via automated optical detection as solid transforms to liquid. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard reference under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Mass difference measured before and after high-temperature ashing to determine inorganic residue content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution at specified concentration and wavelength. |
