Manufacturing Quality Control of QUINOLINE SULPHATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Quinoline Sulfate Content) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH after acid hydrolysis. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction with iodine and sulfur dioxide. |
| Loss on Drying | Gravimetric Analysis | Determines volatile matter by weight loss after heating at specified temperature and time. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration of sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomic absorption of characteristic wavelengths after acid digestion. |
| Sulfate Ion (SO4) Content | Gravimetric Analysis (Barium Sulfate Precipitation) | Determines sulfate as insoluble BaSO4 precipitate formed from reaction with barium chloride. |
| pH of Aqueous Solution | Potentiometric Method | Measures hydrogen ion activity using calibrated pH electrode in standardized aqueous suspension. |
| Melting Point | Capillary Melting Point Determination | Identifies purity and identity by observing temperature range at which solid transitions to liquid. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies quinoline-related impurities using reverse-phase column and UV detection. |
| Residual Solvents | Gas Chromatography (GC) | Detects and quantifies volatile organic solvents (e.g., ethanol, acetone) using headspace GC-FID. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles by analyzing angular scattering pattern of laser beam. |
| Bulk Density | Volumetric Gravimetric Method | Calculates mass per unit volume of freely settled powder in a standardized cylinder. |
