Manufacturing Quality Control of 618442-57-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound by UV absorption at specific wavelength using reverse-phase chromatography with calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities via retention time comparison and peak area integration. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using capillary column and flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (e.g., Pd, Ni, Cu) by plasma ionization and mass spectrometric detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and 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 particulates or phase separation under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular scattering pattern of laser beam. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of powder after standardized tapping to simulate packing behavior. |
| Loss on Drying | Thermogravimetric Analysis | Quantifies volatile content by measuring weight loss upon controlled heating under inert atmosphere. |
