Manufacturing Quality Control of 3-Bromo-2-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 carrier gas. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation followed by mass spectral identification and semi-quantitative assessment of impurities relative to main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvent residues are equilibrated in headspace vial and quantified using calibrated GC-FID or GC-MS. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HBr) using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Sample digested in acid matrix; metals atomized and excited in plasma, with emission intensity measured at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column; chloride quantified by conductivity response relative to calibration standards. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated to 500-600 C in platinum crucible; inorganic residue weighed after cooling in desiccator. |
| Melting Point | Capillary Melting Point Apparatus | 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 passing through a solution, indicating chiral purity and identity. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria (e.g., clear, colorless to pale yellow liquid). |
| Density | Digital Density Meter (Oscillating U-tube) | Density derived from resonant frequency shift of a vibrating U-shaped glass tube filled with sample at controlled temperature. |
