1-Butyl-3-methylimidazolium iodide, CAS: 65039-05-6

Key Applications:

Electrochemical Systems & Redox Chemistry

• Used as a supporting electrolyte and ionic conductor in electrochemical cells, benefiting from its high ionic mobility and thermal stability.
• Employed in redox‑active systems, including iodide/tri‑iodide couples, due to the stabilizing effect of the imidazolium cation on halide species.

Dye‑Sensitized Solar Cells (DSSCs)

• Functions as a key iodide source in liquid electrolytes for DSSCs, enabling efficient charge transport and regeneration of the oxidized dye.
• Enhances device stability through strong ion pairing and low volatility.

Catalysis & Organic Synthesis

• Serves as a halide‑rich ionic medium for nucleophilic substitution, phase‑transfer catalysis, and metal‑catalyzed transformations.
• Provides a tunable, non‑volatile reaction environment that improves selectivity and yields in halide‑dependent reactions.

Solvent & Reaction Medium

• Acts as a polar, aprotic ionic liquid solvent for reactions requiring strong halide presence, including SN1/SN2 pathways and transition‑metal catalysis.
• Supports high‑temperature and microwave‑assisted synthesis due to its thermal robustness.

Materials Processing & Nanomaterials

• Utilized in the synthesis and stabilization of metal nanoparticles, where iodide ions influence nucleation and growth behavior.
• Applied in templating and surface‑modification processes for carbon materials, polymers, and inorganic frameworks.

Electrolytes for Batteries & Energy Storage

• Investigated as a component in electrolytes for next‑generation batteries, where iodide anions contribute to redox‑mediated charge storage mechanisms.
• Offers high ionic conductivity and wide electrochemical windows suitable for experimental energy‑storage architectures.
