Description

N-Phenyl-Bis(Trifluoromethanesulfonimide) is a highly reactive and versatile trifluoromethanesulfonimide (Tf2N) derivative, serving as a key reagent for introducing the non-coordinating, super-acidic bis(triflyl)imide anion. Its primary value lies in its exceptional utility as a precursor for generating ionic liquids, catalysts, and specialty electrolytes with superior thermal stability and conductivity. This compound is essential for researchers and manufacturers in advanced materials science, lithium-ion battery technology, and organic synthesis, particularly for creating novel Lewis acid catalysts and high-performance electrolytes.

Application

• Ionic Liquid Synthesis: A fundamental precursor for creating a wide range of hydrophobic, low-viscosity, and thermally stable ionic liquids with the bis(trifluoromethanesulfonyl)imide anion.
• Lithium-Ion Battery Electrolytes: Used to synthesize lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), a critical salt in high-performance liquid and solid polymer electrolytes due to its high conductivity and electrochemical stability.
• Catalyst & Reagent Preparation: Serves as a starting material for generating strong Lewis acid catalysts and other reactive intermediates used in organic transformations, such as Friedel-Crafts alkylations and acylations.
• Polymer & Material Science: Employed in the development of advanced polymeric materials, including ion-conductive membranes for fuel cells and specialty coatings.
• Pharmaceutical Intermediates: Utilized in the synthesis of complex organic molecules where the introduction of the Tf2N group is required for specific pharmacological activity or stability.

Quality Control

Our N-Phenyl-Bis(Trifluoromethanesulfonimide) is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for research and industrial applications. Each lot is analyzed using advanced techniques including NMR, HPLC, and Karl Fischer titration. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance requirements.

Storage

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