| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm, comparing peak area to a reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities by retention time relative to the main peak; uses gradient elution and UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., THF, DMF, toluene) via headspace injection and flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (Pb, Cd, Hg, As, etc.) after acid digestion by measuring elemental ion signals in plasma. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residual Palladium | ICP-MS | Determines residual Pd from catalytic hydrogenation steps by acid digestion followed by ultra-trace mass spectrometric detection. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation using sodium D-line light source to confirm chiral integrity and absence of racemization. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or foreign matter against established reference standards. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under controlled temperature and vacuum to determine volatile content including moisture and solvents. |
| pH of Solution | Potentiometric pH Measurement | Determines acidity/basicity of a standardized aqueous or aqueous-organic solution using calibrated glass electrode. |
