Manufacturing Quality Control of 7-HYDROXYCOUMARIN-4-ACETIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at ~320 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., hydrolysis products, isomers) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identifies and quantifies residual solvents (e.g., ethyl acetate, methanol) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines trace water content via electrochemical titration using iodine generated in situ; based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies trace heavy metals (e.g., Pb, Cd, Ni, As) after acid digestion using inductively coupled plasma mass spectrometry for multi-element ultratrace detection. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures inorganic residue after high-temperature ashing (500–600 °C); weight difference reflects non-volatile inorganic impurities. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via comparison to reference value (184–187 °C). |
