Manufacturing Quality Control of 4-Carboxylphenylboronic acid pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual starting materials, de-borylated products) via gradient reverse-phase HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, ethyl acetate) using gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Quantifies metal impurities (e.g., Pd, Ni, Fe) after acid digestion by measuring atomic emission intensities at element-specific wavelengths. |
| Residual Boron | ICP-OES | Measures total boron content post-digestion to ensure compliance with inorganic residue limits, using boron-specific emission line. |
| 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 foreign particles under controlled white light against defined reference standards. |
| Loss on Drying | Gravimetric Method | Measures weight loss after drying under specified temperature and vacuum conditions to determine volatile and moisture content. |
| Residual Palladium | ICP-MS | Provides ultra-trace quantification of palladium catalyst residues using mass spectrometric detection of isotopic signals. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH to quantify free carboxylic acid groups, indicating hydrolysis extent of the ester moiety. |
