1-Methyl-1-propylpyrrolidinium bromide, CAS: 608140-09-6

Key Applications

Electrochemical and Energy Applications

• Employed as a supporting electrolyte or ionic additive in electrochemical studies requiring stable, non‑reactive cations.
• Useful in evaluating ion‑transport behavior in prototype ionic liquid systems and mixed‑solvent electrolytes.
• Supports charge‑transfer studies, electrode interface characterization, and conductivity benchmarking.

Materials Science and Polymer Systems

• Incorporated into polymer matrices to tune ionic conductivity, plasticization behavior, and mechanical properties.
• Used in the preparation of ion‑conducting films, membranes, and composite materials for research applications.
• Serves as a structure‑directing ion in templated materials and organized soft‑matter assemblies.

Catalysis and Synthetic Chemistry

• Functions as a phase‑transfer catalyst or ionic medium in reactions requiring enhanced solubility of inorganic species.
• Provides a controlled ionic environment for nucleophilic substitutions, alkylations, and other transformations sensitive to solvent polarity.
• Supports mechanistic studies where quaternary ammonium ions are used as benchmarks or reference cations.

Analytical and Separation Science

• Utilized as an ion‑pairing reagent in chromatography to improve retention and separation of analytes with complementary charge profiles.
• Applied in method development for ion‑exchange and electrophoretic systems requiring stable, well‑defined cations.

General Research and Formulation Uses

• Serves as a precursor or reference compound in the development of new ionic liquids and quaternary ammonium derivatives.
• Useful in solvation, miscibility, and thermodynamic studies involving bromide salts and pyrrolidinium‑based ions.
• Supports formulation screening where cation identity influences viscosity, polarity, or interfacial behavior.
