Manufacturing Quality Control of 3-COUMARANONE
| 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-DAD | Separation and identification of impurities using HPLC coupled with diode array detection, with spectral comparison and relative response factor correction. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents based on calibrated retention times and peak areas. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by sulfuric acid treatment and weighing of residual inorganic ash. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary apparatus with controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria under standardized lighting and viewing conditions. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and identity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination using calibrated glass electrode and pH meter in a saturated aqueous suspension or dilute solution. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume measured by gently pouring material into a calibrated cylinder and leveling the surface without compaction. |
