Manufacturing Quality Control of 851231-30-6
| 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 external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., residual phenol, boronic acid, hydrolysis products) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine consumption in pyridine/methanol buffer. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Residual Palladium | ICP-MS | Measures ultra-trace palladium from cross-coupling catalyst residues using inductively coupled plasma mass spectrometry for high sensitivity. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions after sample dissolution and filtration using suppressed conductivity detection. |
| Sulfate Content | Ion Chromatography | Detects sulfate anions post-dissolution via ion exchange chromatography with conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or foreign matter under controlled white light against defined reference standards. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under specified temperature and vacuum conditions to determine volatile and moisture content. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral impurities or degradation products in solution using sodium D-line illumination. |
