Methyltrioctylammonium triflate, CAS: 121107-18-4

Key Applications:

Phase‑Transfer and Ion‑Exchange Applications

• Functions as a hydrophobic quaternary ammonium triflate salt for transferring anionic species into nonpolar or moderately polar organic media.
• Supports biphasic and multiphasic reaction systems where strong, non‑coordinating anions are required to stabilize reactive intermediates.
• Useful in ion‑exchange processes where a bulky, lipophilic cation paired with a weakly coordinating anion improves selectivity and extraction efficiency.

Catalysis and Organic Synthesis

• Serves as a non‑nucleophilic ionic component in Lewis and Brønsted acid‑mediated transformations.
• Enhances reaction rates in alkylation, acylation, and rearrangement chemistry by providing a stable triflate counterion that does not interfere with catalytic cycles.
• Employed in systems requiring low water activity and high thermal stability.

Solvent and Electrolyte Engineering

• Acts as a structure‑directing ionic additive in nonaqueous electrolyte formulations.
• Supports high‑conductivity media for electrochemical studies where hydrophobicity and anion stability are critical.
• Useful in tailoring viscosity, polarity, and ion‑pairing behavior in mixed organic solvents.

Extraction and Separation Science

• Facilitates selective extraction of metal ions, particularly in systems where the triflate anion improves solubility of metal complexes in organic phases.
• Applied in liquid–liquid extraction workflows for rare‑earth, transition‑metal, and actinide separations.
• Suitable for designing task‑specific ionic liquids for hydrometallurgical operations.

Materials and Polymer Processing

• Functions as a dopant or ionic plasticizer in specialty polymers, membranes, and ionogels.
• Supports fabrication of hydrophobic ionic matrices with enhanced thermal and chemical stability.
• Useful in templating or modifying surface charge in advanced materials.

Analytical and Spectroscopic Uses

• Provides a stable, non‑coordinating triflate environment for NMR, IR, and MS studies of reactive cationic species.
• Employed as an ion‑pairing reagent in chromatographic method development, especially for hydrophobic analytes.
