Manufacturing Quality Control of 569343-09-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, relative to certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual boronic acid, deborylated byproducts) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) by inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Palladium | ICP-OES | Measures palladium catalyst residue using inductively coupled plasma optical emission spectroscopy. |
| 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 of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard references. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under specified vacuum/temperature conditions to determine volatile content. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using Mie scattering theory and diffraction pattern analysis. |
