Manufacturing Quality Control of 3-(Methylsulfonyl)phenylboronic Acid Pinacol Ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, relative to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual boronic acid, deborylated by-products) using gradient HPLC-UV against qualified impurity standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by headspace GC with flame ionization detection, per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based reagent in anhydrous methanol medium. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) after microwave-assisted acid digestion, using isotope-dilution mass spectrometry for ppt-level sensitivity. |
| Residual Palladium | ICP-OES | Measures palladium from cross-coupling catalyst residues post-digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfate Content | Ion Chromatography | Quantifies sulfate ions via conductivity detection following sample dissolution and filtration. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established reference samples. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric Method | Measures weight loss after drying under vacuum at 60 C for 2 hours, indicating volatile and moisture content. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity (if applicable) using sodium D-line light; confirms absence of racemization during synthesis. |
