Industrial Applications of 1,3,5-Phenyltriboronic acid, pinacol ester
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used in synthesizing boronic acid-containing targeted anticancer drugs (e.g., analogues of BTK inhibitors) and as a boronic acid ligand module in PROTAC molecules | Suzuki-Miyaura cross-coupling, serving as a trisubstituted arylboronic acid precursor for constructing complex heterocyclic frameworks |
| Materials Science | Preparation of covalent organic framework (COF) materials as a trivalent node unit | Solvothermal condensation polymerization, forming crystalline porous polymers via reversible boronate esterification with trialdehyde monomers (e.g., 1,3,5-benzenetricarboxaldehyde) |
| Organic Synthesis | Multifunctional coupling reagent for highly selective construction of symmetric trisubstituted aromatic systems | Palladium-catalyzed cross-coupling (e.g., with aryl halides); the pinacol ester group provides excellent air stability and functional group compatibility |
Manufacturing Quality Control of 1,3,5-Phenyltriboronic acid, pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., THF, toluene, methanol) against external calibration standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As, etc.) after acid digestion, using isotopic detection and internal standard correction. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration at 600-700 C, followed by precise weighing of residual residue. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| Bulk Density | USP <616> Tap Density Method | Measurement of mass per unit volume after standardized tapping; used for flow and handling characterization. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dispersed phase using Mie scattering theory and validated optical model. |
| Boron Content | ICP-OES | Quantitative determination of total boron after microwave-assisted acid digestion, measured via boron-specific emission line at 249.773 nm. |
