Manufacturing Quality Control of 5-HYDROXY-3,4-DIHYDRO-1H-QUINOLIN-2-ONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV or HPLC-MS | Separation and detection of structurally related impurities (e.g., starting materials, degradants, isomers) using gradient elution and UV or mass-selective detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., methanol, ethyl acetate, toluene) by gas chromatography with flame ionization detection against calibrated standards. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (e.g., Pb, Cd, Hg, As) at trace levels (ppq–ppt) following acid digestion and isotopic mass spectrometric detection. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water content via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration (~750 °C) followed by precise weighing of residual non-volatile matter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement based on optical observation of solid-to-liquid phase change under controlled heating rate (e.g., 1 °C/min). |
