Manufacturing Quality Control of 3,4-Dimethylphenylboronic acid pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound by UV absorption relative to a calibrated standard curve using reverse-phase chromatography. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities based on retention time and UV response relative to the main peak. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine generated in situ via reaction with water. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pb, Cd, Ni) by mass spectrometric detection of elemental ions after acid digestion. |
| Residual Boron | ICP-OES | Quantifies total boron content by measuring atomic emission intensity at characteristic wavelengths after sample digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride anions using suppressed conductivity detection after anion-exchange separation. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or phase separation under controlled lighting. |
| Loss on Drying | Gravimetric Analysis | Measures mass loss after drying under specified temperature/vacuum conditions to determine volatile content. |
| Residual Palladium | ICP-MS | Quantifies palladium catalyst residue using high-sensitivity mass spectrometry following microwave-assisted acid digestion. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization (if applicable). |
