1-Butyl-3-methylimidazolium bromide, CAS: 85100-77-2

Key Applications:

Solvent & Reaction Medium

• Serves as a polar, non‑volatile ionic liquid solvent for organic synthesis, catalysis, and transition‑metal–mediated transformations.
• Enhances reaction rates and selectivity in nucleophilic substitutions, oxidations, and coupling reactions due to strong ionic solvation and thermal stability.

Electrochemical Systems

• Used as an electrolyte component in electrochemical cells, supercapacitors, and redox systems where high ionic conductivity and wide electrochemical windows are required.
• Supports stable ion transport in dye‑sensitized and perovskite solar cell research.

Dissolution & Processing of Biomass

• Facilitates dissolution of cellulose, lignin, and other biopolymers, enabling biomass fractionation, pretreatment, and derivatization workflows.
• Applied in sustainable materials processing and green‑chemistry extraction systems.

Nanomaterials & Colloids

• Acts as a templating or stabilizing medium for nanoparticles, quantum dots, and metal/metal‑oxide nanostructures.
• Improves dispersion stability and morphology control in colloidal synthesis.

Separation Science

• Employed as a mobile‑phase additive or stationary‑phase modifier in chromatography and capillary electrophoresis to tune selectivity and improve analyte resolution.
• Useful in ionic‑liquid‑based extraction systems for metal ions, dyes, and organics.

Thermal & Phase‑Change Applications

• Utilized in thermal‑storage research due to its high thermal stability and tunable phase behavior.
• Supports development of ionic‑liquid‑based heat‑transfer fluids.
