Manufacturing Quality Control of 9,9-Diphenylfluorene-2-Boronic acid pinacol ester
| 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 structurally related impurities using gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine consumption 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 Boron | ICP-OES | Measures total boron content by atomic emission from plasma-excited atoms following sample dissolution. |
| 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 controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting and against white background. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under specified temperature and vacuum to determine volatile content. |
| Residual Palladium | ICP-MS | Quantifies palladium catalyst residue using isotope-specific detection after microwave-assisted acid digestion. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
