Manufacturing Quality Control of NAPHTHALENE-2-BORONIC 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 based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual 2-naphthol, boronic acid, dimer) using gradient HPLC-UV with suitable column and mobile phase. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generated electrochemically in presence of water. |
| Heavy Metals | ICP-MS | Quantifies toxic elements (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Residual Palladium | ICP-OES | Measures palladium from cross-coupling catalyst residues after microwave-assisted acid digestion 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 at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| Loss on Drying | Gravimetric Analysis | Measures volatile content by weight loss after drying at specified temperature (e.g., 105 C) under vacuum for fixed duration. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to detect chiral impurities or enantiomeric excess, though compound is achiral; used for consistency check. |
| Residual Boric Acid | Acid-Base Titration | Quantifies free boric acid by mannitol-enhanced titration with standardized NaOH solution using phenolphthalein indicator. |
