| Catalyst Ligand | Employed as a ligand for transition metal catalysts to enhance catalytic efficiency and selectivity | In homogeneous catalysis, coordinates to metal centers such as palladium or nickel to modulate catalytic activity and stereoselectivity |
| Fine Chemicals | Used to prepare functionalized aromatic compounds | The boronate ester group participates in multiple coupling reactions to enable directed synthesis of multifunctional molecules |
Manufacturing Quality Control of 939430-30-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV against qualified impurity standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by headspace GC with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Residual Boron | ICP-OES | Measures total boron content post-digestion using inductively coupled plasma optical emission spectroscopy at 249.77 nm line. |
| 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 of solid-to-liquid transition using calibrated capillary apparatus 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 loss by weight difference after drying at 105 C for 2 hours under vacuum. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution using Mie scattering theory with helium-neon laser source. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity (if applicable) using sodium D-line light in solution at specified concentration and path length. |
