Manufacturing Quality Control of 4-(TRIMETHYLSILYL)PHENYLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., THF, toluene) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Measures trace metal impurities after acid digestion by inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Residual Boric Acid | Acid-Base Titration | Quantifies free boric acid by titration with standardized NaOH using mannitol to enhance acidity, detected potentiometrically or with phenolphthalein. |
| Residual Siloxanes | GC-MS | Identifies and quantifies volatile siloxane impurities (e.g., hexamethyldisiloxane) by gas chromatography coupled to mass spectrometry. |
| Chloride Ion Content | Ion Chromatography | Separates and quantifies chloride anions using suppressed conductivity detection after aqueous extraction and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Appearance (Color & Clarity) | Visual Inspection | Assesses physical state, color (compared to APHA scale), and presence of particulates or haze in solution under controlled lighting. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying under vacuum at 60 C for 2 hours, indicating volatile content and moisture. |
| Residual Palladium | ICP-OES | Quantifies palladium catalyst residue after microwave-assisted nitric/hydrochloric acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Organoboron By-products (e.g., bis-boronic esters) | HPLC-ELSD | Detects non-UV-active boron-containing impurities using high-performance liquid chromatography with evaporative light scattering detection. |
