Description

1-Ethynyl-4-((4-Methoxyphenyl)ethynyl)benzene is a high-purity organic building block featuring a conjugated diyne structure, which is critical for advanced material synthesis. This compound matters for its role as a key precursor in the development of organic semiconductors, nonlinear optical materials, and metal-organic frameworks (MOFs). It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures.

Application

• Organic Electronic Materials: Serves as a core building block for conjugated polymers and small molecules used in organic light-emitting diodes (OLEDs), field-effect transistors (OFETs), and photovoltaic cells.
• Pharmaceutical Intermediates: Used in the synthesis of potential drug candidates, particularly those requiring rigid, linear aromatic scaffolds for target binding.
• Metal-Organic Frameworks (MOFs): Acts as a functional organic linker to create porous coordination polymers with tailored properties for gas storage, separation, or catalysis.
• Nonlinear Optical (NLO) Materials: Employed in the development of materials for frequency doubling, optical switching, and electro-optic modulation due to its extended π-conjugation.
• Agrochemical Synthesis: Utilized as an intermediate in creating novel active ingredients with specific biological activity.
• Academic & Industrial Research: A valuable reagent for exploring new reactions in synthetic chemistry, such as Sonogashira coupling and click chemistry.

Quality Control

Our 1-Ethynyl-4-((4-Methoxyphenyl)ethynyl)benzene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure compliance with exacting R&D and production standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Keep away from heat, sparks, and open flame. Due to its sensitivity, minimize exposure to air and moisture during handling.
