1-Methyl-1-propylpyrrolidinium chloride, CAS: 528818-82-8

Key Applications:

Electrochemistry & Energy Storage

• Employed as an ionic liquid precursor or supporting electrolyte in aqueous and mixed‑solvent electrochemical systems.
• Enhances ionic conductivity and electrode interfacial stability in redox‑flow, metal‑ion, and hybrid aqueous battery research.
• Used in electrodeposition studies where chloride coordination influences metal nucleation and morphology.

Catalysis & Reaction Media

• Serves as a polar, non‑volatile medium for transition‑metal catalysis, phase‑transfer catalysis, and halide‑assisted transformations.
• Supports selective organic transformations where chloride activity modulates reaction pathways.
• Utilized in mechanistic studies probing ion–pairing, solvation, and microenvironment effects.

Polymer & Materials Science

• Acts as a structure‑directing additive in polymer electrolytes, ion‑conducting membranes, and block‑copolymer assemblies.
• Incorporated into ionogels and hybrid materials to tune mechanical strength, ionic mobility, and thermal stability.
• Used in templating and self‑assembly studies where pyrrolidinium cations influence nanoscale ordering.

Solvent Extraction & Separation Science

• Applied in liquid–liquid extraction systems for selective metal ion coordination and chloride‑driven speciation control.
• Supports separation processes requiring high polarity, low volatility, and tunable ion‑pair interactions.

Spectroscopy & Fundamental Studies

• Used as a model pyrrolidinium ionic liquid for NMR, IR, Raman, and dielectric spectroscopy to probe ion dynamics, hydrogen bonding, and solvation structure.
• Supports computational and experimental benchmarking of cation–anion interactions in chloride‑based ionic liquids.
