Manufacturing Quality Control of 7-Methoxy-3,4-dihydro-1H-quinolin-2-one
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-DAD | Identifies and quantifies impurities by retention time and UV spectral matching using diode-array detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, toluene) via gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol/pyridine medium. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method per USP <741>. |
| Loss on Drying | Gravimetric Method | Measures volatile matter loss by weight difference before and after drying at 105 C for 2 hours under vacuum. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by angular rotation of plane-polarized light in solution at specified concentration and wavelength (589 nm). |
| Residue on Ignition | Gravimetric Ashing | Quantifies inorganic residue after high-temperature incineration (600-800 C) followed by weighing. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersion using Mie scattering theory to determine volume-weighted particle size distribution. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a saturated aqueous suspension (10 mg/mL) using calibrated pH electrode. |
