Description

3,4,5,6-Tetrafluorobenzene-1,2-Diylbis(Trimethylstannane) is a specialized organotin compound featuring a perfluorinated benzene core, serving as a critical building block in advanced organic synthesis. Its value lies in its dual trimethylstannyl groups, which enable efficient Stille cross-coupling reactions for constructing complex fluorinated aromatic systems. This high-purity reagent is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries developing novel fluorinated compounds with enhanced properties.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of fluorinated active pharmaceutical ingredients (APIs) and drug candidates via Stille coupling.
• Agrochemical Synthesis: Used to create novel fluorinated pesticides, herbicides, and fungicides with improved efficacy and environmental profiles.
• Organic Electronic Materials: Building block for fluorinated conjugated polymers and small molecules used in OLEDs, OFETs, and photovoltaic cells.
• Liquid Crystal & Advanced Material Development: Enables the introduction of fluorinated aromatic units to tune the dielectric, optical, and thermal properties of functional materials.
• Catalyst & Ligand Precursor: Serves as a starting material for synthesizing specialized organometallic catalysts and ligands.
• Fluorinated Polymer Chemistry: Monomer or comonomer for synthesizing high-performance, fluorinated polymers with exceptional chemical and thermal stability.

Quality Control

Our 3,4,5,6-Tetrafluorobenzene-1,2-Diylbis(Trimethylstannane) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for sensitive coupling reactions. Each lot is characterized by advanced analytical techniques including NMR (1H, 13C, 19F, 119Sn), GC-MS, and elemental analysis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (argon or nitrogen) due to its moisture-sensitive and potentially air-sensitive nature. Keep the container tightly sealed when not in use to prevent degradation from moisture and oxygen.
