1-Ethyl-3-methylimidazolium dicyanamide, CAS: 370865-89-7

Key Applications:

Advanced Electrolytes and Energy Storage

• Serves as a high‑conductivity ionic liquid electrolyte for lithium‑ion, sodium‑ion, and aluminum‑ion batteries, offering low viscosity and wide electrochemical stability.
• Used in supercapacitor electrolytes to enhance ion mobility and reduce internal resistance.
• Supports redox‑flow battery systems where low‑viscosity ionic liquids improve mass transport.

Thermal Management & Heat‑Transfer Media

• Functions as a thermally stable heat‑transfer fluid in high‑temperature environments.
• Applied in thermoelectric devices and phase‑change systems where low volatility and high thermal stability are required.

Catalysis & Reaction Media

• Acts as a polar, aprotic solvent for transition‑metal catalysis, organocatalysis, and C–C coupling reactions.
• Enhances reaction rates in nucleophilic substitution, cycloaddition, and ionic polymerization due to its strong coordinating dicyanamide anion.
• Used as a medium for biocatalysis, improving enzyme stability in non‑aqueous systems.

Biomass Processing & Green Chemistry

• Effective in cellulose dissolution, pretreatment, and fractionation for biofuel and biopolymer production.
• Supports lignin extraction and selective depolymerization pathways.
• Enables CO₂ capture and separation due to favorable anion–gas interactions.

Materials Science & Surface Engineering

• Used in nanoparticle synthesis (e.g., metal, metal oxide, and carbon nanostructures) where ionic‑liquid templating improves size control.
• Serves as a medium for electrodeposition of metals and alloys.
• Applied in lubrication systems as an anti‑wear additive or base fluid due to low viscosity and high polarity.

Analytical Chemistry

• Utilized in sample preparation, extraction, and ion‑pairing workflows.
• Enhances performance in chromatographic separations and mass spectrometry ionization.
