Manufacturing Quality Control of 5-BROMO-2-PHENYLPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., starting materials, intermediates, isomers) using gradient HPLC-UV against qualified reference standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, toluene, DMF) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion, measuring metal contaminants (e.g., Pb, Cd, Ni, Fe) by atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection, calibrated with NaCl standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white light and against reference samples. |
| Loss on Drying | Gravimetric Method | Measurement of mass loss after drying under vacuum at specified temperature/time, indicating volatile content including moisture and residual solvents. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, used to detect chiral impurities or enantiomeric excess if applicable. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in suspension using Mie scattering theory and diffraction pattern analysis. |
| pH of Aqueous Slurry | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous slurry using calibrated glass electrode pH meter. |
