Manufacturing Quality Control of 3,5-Bis(methoxycarbonyl)phenylboronic acid pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specified wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., mono-ester, hydrolyzed acid, residual boronic acid) via gradient elution and peak area comparison. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) using flame ionization detection with headspace sampling. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration based on iodine consumption in pyridine-methanol buffer. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion using plasma excitation and atomic emission detection. |
| Residual Boron | ICP-OES | Measures total boron content post-digestion to verify stoichiometry and detect excess boron-containing impurities. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residual Palladium | ICP-MS | Detects trace palladium catalyst residues with high sensitivity via mass spectrometric detection of Pd isotopes. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and optical observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and against reference standards. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using Mie scattering theory and angular intensity analysis. |
| Loss on Drying | Gravimetric Analysis | Determines volatile content by weight loss after controlled heating at specified temperature and time under vacuum or nitrogen. |
