1-(3-Cyanopropyl)pyridinium bis(trifluoromethylsulfonyl)imide
1-(3-Cyanopropyl)pyridinium bis(trifluoromethylsulfonyl)imide (CAS 820972-37-0) is a nitrile-functionalised pyridinium ionic liquid with the empirical formula C11H11F6N3O4S2 and a molecular weight of 427.34 g/mol. Pairing a cyanopropyl-tagged pyridinium cation with the hydrophobic bis(trifluoromethylsulfonyl)imide (NTf2) anion, it is a task-specific room-temperature ionic liquid valued for its low volatility, wide liquid range and tunable solvation. Tech Serve Solutions supplies it as a research-grade reagent for synthesis, electrochemistry and separation studies.

Task-specific ionic liquid solvent
Serves as a designer reaction medium for organic synthesis and catalysis, where its negligible vapour pressure and broad liquid range allow it to replace volatile organic solvents. The pendant nitrile group offers an additional coordination site for tuning solvation and metal interactions.
Electrochemistry and electrolytes
The bis(trifluoromethylsulfonyl)imide anion gives good ionic conductivity, a wide electrochemical window and thermal stability, making this ionic liquid a candidate electrolyte component for electrodeposition, batteries, supercapacitors and other electrochemical research.
Separation and extraction media
As a hydrophobic NTf2-based ionic liquid, it is studied in liquid-liquid extraction and as a stationary or extracting phase, where the cyano functionality can enhance selectivity toward specific solutes and metal ions.
Materials and interface research
Used in laboratory studies of functionalised ionic liquids, including surface, lubrication and gas-absorption investigations, where the nitrile-tagged pyridinium cation provides a handle for modifying physicochemical behaviour.
