Description

3,3''-Bis-(Trimethylsilyl)Biphenyl-4,4''-Diyl Bis(Trifluoromethanesulfonate) is a high-value, multi-functional organosilicon intermediate and electrophilic arylating agent. Its core value lies in its dual reactive triflate groups, which enable efficient cross-coupling reactions, making it a critical building block for advanced material synthesis. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and organic electronics industries who require precise and reliable precursors for complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in Suzuki, Stille, and other palladium-catalyzed cross-couplings for synthesizing novel active pharmaceutical ingredients (APIs) and drug candidates.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and pesticides that require specific biphenyl-based structures.
• Organic Electronic Materials: Acts as a monomer or building block for conjugated polymers, OLED (Organic Light-Emitting Diode) materials, and other functional organic semiconductors.
• Ligand and Catalyst Development: Employed in the synthesis of sophisticated ligands for asymmetric catalysis and novel organometallic complexes.
• Advanced Polymer Chemistry: Facilitates the creation of specialty polymers with tailored properties for high-performance coatings and engineering plastics.
• Chemical Research & Development: A versatile reagent for academic and industrial R&D focused on new organic synthesis methodologies and material science.

Quality Control

Our 3,3''-Bis-(Trimethylsilyl)Biphenyl-4,4''-Diyl Bis(Trifluoromethanesulfonate) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and batch-to-batch consistency suitable for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
