Industrial Applications of 267221-88-5
| Industry | Application | Process |
|---|---|---|
| Organic Optoelectronic Materials | Hole-transport layer (HTL) material for OLEDs, enhancing device efficiency and stability | Film formation via vacuum thermal evaporation or solution spin-coating; used as a small-molecule HTL or as a host matrix in doped systems |
| Organic Synthesis | Boronic ester coupling reagent for Suzuki-Miyaura cross-coupling to construct conjugated architectures such as biphenyls and triarylamines | Coupling with aryl halides (e.g., bromobenzene, 1-iodonaphthalene) under basic conditions (Na₂CO₃/K₃PO₄), catalyzed by Pd(PPh₃)₄ or Pd(dppf)Cl₂ |
| Pharmaceutical Intermediates | Key building block for potential drug molecules containing triarylamine motifs (e.g., kinase inhibitors, antitumor candidates) | Introduction of a diphenylaminophenyl moiety via Suzuki coupling, followed by further functional group transformations (e.g., nitration, reduction, acylation) to assemble the active molecular scaffold |
Manufacturing Quality Control of 267221-88-5
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase column with methanol/water or acetonitrile/water as the mobile phase, and UV detection (e.g., 254 nm) to quantify the main peak purity and assess impurity levels. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Utilizes ¹H NMR and ¹³C NMR to analyze chemical shifts of hydrogen and carbon atoms, confirming molecular structure and substitution positions. |
| Molecular Weight Confirmation | Mass Spectrometry (MS) | Employs ESI-MS or APCI-MS to determine the molecular ion peak, verifying that the molecular weight matches the theoretical value ([M+H]⁺ or [M+Na]⁺). |
| Impurity Identification | Liquid Chromatography-Mass Spectrometry (LC-MS) | Separates components via HPLC followed by MS detection, enabling identification and qualitative analysis of unknown impurities, aiding in the determination of synthetic by-products or degradation products. |
| Water Content | Karl Fischer Titration | Determines trace water content using either volumetric or coulometric methods, ensuring compliance with loss-on-drying or moisture limit requirements. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection with FID detection to detect common organic solvent residues (e.g., toluene, THF, DMF) according to pharmacopoeial methods. |
| Melting Point Determination | Capillary Melting Point Apparatus | Measures the melting temperature range as a physical constant for preliminary identification and assessment of product consistency. |
| Appearance and Physical Properties | Visual Inspection and Microscopic Observation | Observes color, crystal form, particle morphology, and other physical characteristics to ensure conformity with standard descriptions (e.g., white to pale yellow crystalline powder). |
| Thermal Stability / Degradation Study | Accelerated Stability Testing + HPLC Monitoring | Stores samples under high temperature and humidity conditions, with periodic sampling and HPLC analysis to monitor changes in main component and formation of degradation products. |
| Chiral Purity (if applicable) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | If chiral centers are present, uses chiral columns to separate enantiomers and assess optical purity (ee value). |
