Manufacturing Quality Control of COUMARIN 6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies coumarin 6 by separation on a reversed-phase column and UV absorbance detection at characteristic wavelength. |
| Related Substances | HPLC-DAD | Identifies and quantifies structurally related impurities using diode array detection for spectral confirmation. |
| Residual Solvents | GC-FID | Measures volatile organic solvents by gas chromatographic separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment and high-temperature incineration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Specific Optical Rotation | Polarimetry | Measures angle of rotation of plane-polarized light induced by chiral molecules in solution. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after high-temperature ignition without sulfuric acid pretreatment. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles by measuring angular variation in laser light scattering. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determines hydrogen ion activity in a saturated aqueous suspension using calibrated pH electrode. |
