Manufacturing Quality Control of 4-Nitrophenylboronic acid pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorbance at specific wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities via retention time comparison and peak area integration. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using capillary column and flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Determines total elemental metal content (e.g., Pb, Cd, Ni) after acid digestion by atomic emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residual Palladium | ICP-MS | Quantifies trace palladium from cross-coupling catalysts using high-sensitivity mass spectrometry after digestion. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid based on optical observation of phase change. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after heating under specified conditions to determine volatile and moisture content. |
| Specific Optical Rotation | Polarimetry | Measures angle of rotation of plane-polarized light induced by chiral impurities or enantiomeric excess. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension by analyzing angular scattering pattern of laser beam. |
