Manufacturing Quality Control of ETHYL COUMARIN-3-CARBOXYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 310 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., ethanol, ethyl acetate) against calibration curves. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, As, Hg, and Cr after acid digestion, based on atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential inflection due to AgCl precipitation. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C after sulfuric acid treatment; residue mass measured as inorganic sulfate ash content. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration measuring water via iodine-sulfur dioxide reaction in pyridine-methanol solvent system. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid material against established reference standards under controlled lighting. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measurement of mass loss upon heating to 105 C for 2 hours, reflecting volatile content including residual moisture and low-boiling impurities. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C using sodium D-line (589 nm) to assess chiral purity and identity. |
| pH of Aqueous Suspension | pH Meter | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode per EP 2.2.3. |
