Description

trans-1,2-Bis(Diphenylphosphino)Ethylene is a versatile and highly valuable bidentate phosphine ligand widely used in coordination chemistry and catalysis. Its primary value lies in its ability to chelate transition metals, forming stable complexes that are crucial for a variety of cross-coupling and hydrogenation reactions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise control over catalytic processes to synthesize complex organic molecules.

Application

• Homogeneous Catalysis: A key ligand in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Stille) for C-C bond formation in fine chemical synthesis.
• Pharmaceutical Intermediates: Used in the catalytic production of active pharmaceutical ingredients (APIs) and complex drug candidates.
• Agrochemical Synthesis: Employed as a catalyst component in the manufacture of advanced pesticides and herbicides.
• Material Science: Facilitates the synthesis of organic light-emitting diodes (OLEDs) and other functional materials via metal-mediated reactions.
• Hydrogenation Catalysis: Acts as a ligand for rhodium or ruthenium complexes in asymmetric hydrogenation reactions to produce chiral molecules.
• Academic & Industrial R&D: A fundamental reagent for developing new catalytic systems and methodologies in chemistry laboratories.

Quality Control

Our trans-1,2-Bis(Diphenylphosphino)Ethylene is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for demanding catalytic applications. Each lot is analyzed using advanced techniques including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation, the container should be purged with inert gas after each use to maintain product integrity.
