Applications

Triethylammonium trifluoromethanesulfonat, CAS: 35895-69-3

Key Applications:

Catalysis and Organic Synthesis

  • Functions as a proton source in acid‑catalyzed transformations, including esterifications, dehydrations, rearrangements, and cyclizations.
  • Serves as a bench‑stable alternative to triflic acid, offering controlled acidity without handling hazards associated with strong mineral acids.
  • Useful in activation of alcohols and carbonyls, enabling selective formation of esters, ethers, and acetal derivatives.
  • Employed in ionic liquid synthesis as a precursor or counterion for generating OTf‑based salts.
  • Supports Friedel–Crafts‑type reactions requiring a strong, non‑coordinating acid environment.

Polymer and Materials Chemistry

  • Acts as a dopant or proton source in conductive polymers such as polyaniline and polypyrrole, improving conductivity and film uniformity.
  • Used in ion‑conducting matrices and proton‑exchange materials, leveraging the mobility and stability of the triflate anion.
  • Facilitates surface modification and acid‑assisted crosslinking in polymer processing.

Electrochemistry

  • Provides a high‑purity triflate anion for electrolyte formulations requiring low nucleophilicity and high oxidative stability.
  • Supports proton‑coupled electron transfer studies and acid‑dependent redox processes.

Fuel Cells

  • Serves as a proton donor or acidity‑modifying additive in non‑aqueous and hybrid proton‑exchange membrane (PEM) systems, where controlled Brønsted acidity is required.
  • Used in ionic‑liquid‑modified membranes to enhance proton mobility and thermal stability under anhydrous or low‑humidity conditions.
  • Supports development of high‑temperature PEM materials, leveraging the thermal stability and low coordinating nature of the triflate anion.
  • Functions as a component in proton‑conducting polymer blends, improving conductivity and membrane durability in research‑grade fuel cell architectures.

Solvent and Reaction Medium Applications

  • Enhances solubility of polar substrates in mixed organic media.
  • Used to tune acidity in non‑aqueous systems where water‑sensitive substrates are present.

Analytical and Laboratory Use

  • Serves as a calibration or reference acid in studies involving Brønsted acidity scales in organic solvents.
  • Useful for controlled pH adjustment in specialized reaction systems where inorganic acids are incompatible.
