Description

4-((4-Ethynylphenyl)Ethynyl)Benzenamine is a specialized aromatic amine derivative featuring dual ethynyl functionalities, making it a valuable building block in advanced organic synthesis. Its conjugated structure and terminal alkyne groups are critical for constructing complex molecular architectures, particularly in materials science and pharmaceutical research. This high-purity intermediate is essential for researchers and manufacturers in the fields of organic electronics, polymer chemistry, and the development of novel active pharmaceutical ingredients (APIs).

Application

• Organic Electronic Materials: Serves as a key monomer or cross-linking agent in the synthesis of conjugated polymers and small molecules for Organic Light-Emitting Diodes (OLEDs), Organic Photovoltaics (OPVs), and Field-Effect Transistors (OFETs).
• Pharmaceutical Intermediates: Used in the research and development of new drug candidates, leveraging its amine and alkyne groups for click chemistry and other bio-conjugation strategies.
• Advanced Polymer Synthesis: Acts as a building block for high-performance polymers, including polyimides and polyamides, where its rigid, linear structure can enhance thermal stability and mechanical properties.
• Metal-Organic Frameworks (MOFs): Employed as an organic linker in the construction of MOFs for gas storage, separation, and catalysis applications.
• Surface Functionalization: Utilized to modify material surfaces (e.g., gold, silicon) via its terminal alkyne groups, enabling the creation of tailored interfaces for sensors and diagnostic devices.
• Liquid Crystal and Nonlinear Optical Materials: A precursor in the development of materials with specific optical properties due to its extended π-conjugated system.

Quality Control

Our 4-((4-Ethynylphenyl)Ethynyl)Benzenamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR), to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) with detailed specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be sealed immediately after use to minimize exposure to air.
