Manufacturing Quality Control of 2-Bromo-4-methylpyridine
| 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 using a calibrated column and temperature program. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities by retention time and UV absorbance relative to the main peak. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling and FID | Volatile solvent residues are vaporized in headspace vial and quantified via calibration curves. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., HBr, pyridinium salts) using standardized sodium hydroxide and phenolphthalein indicator. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection after acid digestion; emission intensity at characteristic wavelengths correlates with metal concentration. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Anion separation on ion-exchange column followed by quantitative detection via suppressed conductivity. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample ignited at 700-800 C; residue weight measured after cooling in desiccator to determine non-volatile inorganic content. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral compounds in solution at specified wavelength and temperature. |
| Appearance | Visual Inspection in Standard Light | Assessment of physical state, color, and clarity against established reference standards under controlled daylight-equivalent illumination. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determination from oscillation period of a U-shaped tube filled with sample, correlated to density via calibration with air/water. |
