Manufacturing Quality Control of 7-METHYLCOUMARIN
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 320 nm. |
| Appearance | Visual Inspection | Assessment of physical state and color against established reference samples under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Determination | Measurement of temperature range over which solid transitions to liquid, indicating crystallinity and purity. |
| Loss on Drying | Gravimetric Analysis (105 C, 2 h) | Determination of volatile content by mass loss after standardized heating and cooling under controlled humidity. |
| Residue on Ignition | Sulfated Ash Test | Quantification of non-volatile inorganic impurities remaining after high-temperature combustion and sulfuric acid treatment. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) via atomic emission spectroscopy after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Mass measurement of inorganic residue following ignition and sulfuric acid treatment, expressed as percentage. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities using diode-array detection and retention time matching. |
| Water Content | Karl Fischer Titration | Volumetric determination of water based on stoichiometric reaction with iodine in pyridine-methanol medium. |
| Organic Volatile Impurities | GC-FID | Detection and quantification of residual solvents using flame ionization detection after headspace or direct injection. |
| Particle Size Distribution | Laser Diffraction | Analysis of size distribution in dispersed powder sample by measuring angular variation in laser light scattering. |
