Industrial Applications of 922706-40-9
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used as a boronic acid coupling reagent in Suzuki-Miyaura cross-coupling reactions to construct C–C bonds for synthesizing fluorene-containing drug candidates (e.g., kinase inhibitors, GPCR modulators) | Undergoes coupling with aryl/heteroaryl halides or pseudohalides in the presence of palladium catalysts (e.g., Pd(dppf)Cl₂, Pd(PPh₃)₄), under basic conditions (e.g., Na₂CO₃, K₃PO₄) and in organic solvents (e.g., 1,4-dioxane, toluene) |
| Organic Optoelectronic Materials | Used to synthesize fluorene-based conjugated polymers and small-molecule emissive materials for OLED emissive layers, hole-transport layers, and interfacial modification layers in perovskite solar cells | Introduces the 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)fluorene unit into conjugated backbones via Suzuki coupling, followed by purification, film formation (spin-coating or thermal evaporation), and device fabrication |
| Agrochemical Intermediates | Serves as a structural building block in structure–activity relationship studies and structural optimization of novel fluorene-containing heterocyclic insecticides or fungicides | Incorporates substituted aryl groups via Suzuki coupling within agrochemical synthesis routes, followed by functional group transformations (e.g., nitration, reduction, acylation) to yield target bioactive molecules |
Manufacturing Quality Control of 922706-40-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual starting materials, by-products) using gradient HPLC-UV with system suitability criteria. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, heptane) by headspace GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Heavy Metals | ICP-MS | Quantifies trace metals (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Residual Palladium | ICP-OES | Measures palladium residue from Suzuki coupling catalysts using inductively coupled plasma optical emission spectroscopy. |
| 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 defined standards. |
| Loss on Drying | Gravimetric Heating | Measures weight loss after drying at specified temperature (e.g., 60 C under vacuum) to determine volatile matter content. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization (if applicable). |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using Mie scattering theory and validated instrument calibration. |
