Manufacturing Quality Control of 2-HYDROXYQUINOLINE-4-CARBOXYLIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, DMF) based on calibrated external standards. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using isotopic dilution or external calibration. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified via calibration curve with sodium chloride standard. |
| Sulfate Content | Ion Chromatography | Separation and conductivity detection of sulfate ions in aqueous extract; quantified via calibration curve with sodium sulfate standard. |
| Loss on Drying | Gravimetric Method | Measurement of mass loss after drying under controlled temperature and vacuum; reflects volatile content and residual moisture. |
| Residue on Ignition | Gravimetric Method | Determination of inorganic ash content by high-temperature incineration followed by weighing of the residue. |
| pH of Aqueous Suspension | Potentiometric Titration | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid-to-liquid phase change occurs. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed suspension. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration measuring water via iodine-sulfur dioxide reaction in anhydrous methanol-based reagent. |
