Manufacturing Quality Control of 325142-91-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by retention time and UV absorbance relative to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities based on chromatographic separation and UV response. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents using flame ionization detection after gas chromatographic separation. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Determines trace metal concentrations by atomizing and ionizing the sample, then detecting elemental ions by mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration followed by precise weighing of residual solids. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Specific Optical Rotation | Polarimetry | Measures degree of rotation of plane-polarized light caused by chiral compounds in solution. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles by analyzing angular variation in laser light scattering. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension using calibrated glass electrode. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of powder after standardized mechanical tapping to simulate packing behavior. |
