1-Methyl-1-propylpyrrolidinium dicyanamide, CAS: 327022-60-6

Key Applications:

Electrochemical Systems

• Serves as a non‑volatile electrolyte component in advanced battery research, particularly in systems requiring high ionic conductivity and wide electrochemical stability windows.
• Used in supercapacitor and hybrid capacitor studies where DCA⁻ enhances charge transport and reduces viscosity relative to other ionic liquids.
• Functions as a medium for electrodeposition of metals and alloys, enabling smooth, uniform films under water‑free conditions.

Catalysis and Synthesis

• Acts as a polar, aprotic reaction medium for transition‑metal catalysis, including C–C and C–N bond‑forming reactions.
• Supports organocatalytic transformations where the DCA⁻ anion can modulate reaction pathways through weak coordination.
• Employed in mechanistic studies of ionic‑liquid‑assisted catalysis due to its tunable solvation environment.

Separation and Extraction

• Utilized in liquid–liquid extraction of metal ions, especially for systems requiring selective coordination by the dicyanamide anion.
• Applied in separation of organic compounds where low viscosity and high polarity improve mass transfer and phase behavior.

Materials Science and Polymer Processing

• Used as a processing aid and plasticizing medium for polymer synthesis, including ion‑conductive polymer blends.
• Serves as a solvent or co‑solvent for nanoparticle dispersion and surface modification studies.
• Supports fabrication of ionic‑liquid‑based gels and composite electrolytes.

Thermal and Transport Studies

• Selected for fundamental investigations of ionic‑liquid structure–property relationships, including viscosity, conductivity, and ion‑pairing behavior.
• Used in modeling and simulation validation due to its well‑characterized pyrrolidinium–DCA framework.
