Industrial Applications of 4-ISOXAZOLEBORONIC ACID PINACOL ESTER
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Boronic ester building block for Suzuki-Miyaura cross-coupling to synthesize active pharmaceutical ingredients (APIs) containing isoxazole rings, including intermediates for anticancer, anti-inflammatory, and central nervous system drugs | Cross-coupling with aryl/heteroaryl halides under palladium catalysis (e.g., Pd(dppf)Cl₂), typically conducted at 80–100 °C in basic conditions (e.g., K₂CO₃, Cs₂CO₃) and inert solvents (e.g., 1,4-dioxane, DMF) |
| Pesticide R&D | Construction of bioactive isoxazole-based agrochemical scaffolds, such as fungicidal and insecticidal candidate molecules | Participation in metal-catalyzed C–C bond formation to introduce substituted isoxazole moieties onto heterocyclic or aromatic cores, thereby optimizing physicochemical properties and target-binding activity |
| Materials Science | Functional monomer for electron-transport layers in organic light-emitting diodes (OLEDs) and conjugated polymers, enhancing carrier mobility and thermal stability of devices | Suzuki coupling to incorporate isoxazole boronic ester units into conjugated backbones (e.g., fluorene or carbazole derivatives), enabling precise energy-level tuning and thin-film morphology optimization |
Manufacturing Quality Control of 4-ISOXAZOLEBORONIC ACID PINACOL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at 210-230 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities (e.g., residual starting materials, de-boronated by-products, isomers) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., THF, toluene, ethyl acetate) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagents; based on stoichiometric reaction of water with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Measures total content of regulated metals (e.g., Pb, Cd, Ni, Fe) after acid digestion by optical emission spectroscopy detecting element-specific atomic emission lines. |
| Residual Boron | ICP-OES | Quantifies total boron content post-digestion using characteristic boron emission line (249.773 nm) to confirm complete esterification and absence of free boric acid. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities affecting lattice integrity. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of bulk sample against established reference (white to off-white crystalline powder, free from visible particulates or discoloration). |
