Manufacturing Quality Control of 8-Hydroxyquinoline sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (8-Hydroxyquinoline Sulfate) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH after dissolution and neutralization. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction with iodine in a methanol-based reagent. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metals using plasma-induced atomic emission spectroscopy. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Residue on Ignition | Weight Loss on Ignition | Measures non-volatile inorganic impurities by weight difference before and after high-temperature ashing. |
| Chloride Impurity | Argentometric Titration | Determines chloride ions by titration with silver nitrate using potassium chromate indicator. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection. |
| pH of Aqueous Solution | Potentiometric Measurement | Measures hydrogen ion activity using calibrated glass electrode in a defined aqueous suspension. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser light through dispersed sample. |
| Melting Point | Capillary Melting Point Determination | Identifies purity and identity by observing temperature range at which solid transitions to liquid. |
| Loss on Drying | Thermogravimetric Analysis | Quantifies volatile matter by measuring weight loss under controlled heating and airflow conditions. |
| Microbial Limits | Membrane Filtration | Detects and enumerates aerobic microorganisms using sterile filtration and culture on appropriate agar media. |
