| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, degradants) via gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) using inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Palladium | ICP-OES | Measures palladium content from catalyst residues via plasma excitation and atomic emission detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| 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. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under specified temperature/vacuum to determine volatile and moisture content. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and detect racemization (if applicable). |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using angular scattering pattern analysis. |
