Manufacturing Quality Control of 5-BROMO-8-METHYL-QUINOLINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., bromination by-products, unreacted intermediates) using gradient HPLC-UV with suitable column and mobile phase. |
| Residual Solvents | GC-FID | Measures residual solvents (e.g., toluene, DMF, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Quantifies total heavy metals (e.g., Pb, Cd, Ni, Fe) after acid digestion by inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection after sample dissolution and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Appearance | Visual Inspection | Assesses physical state, color, and homogeneity against established reference standards under controlled lighting conditions. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under specified temperature and vacuum/time conditions to determine volatile content. |
| Residue on Ignition | Sulfated Ash Test | Quantifies non-volatile inorganic residue after high-temperature ignition following sulfuric acid treatment. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dispersed suspension using angular scattering pattern of laser beam. |
| Specific Optical Rotation | Polarimetry | Determines optical activity using sodium D-line light passing through solution in a polarimeter cell; indicates chiral purity if applicable. |
