1-Methyl-1-propylpyrrolidinium iodide, CAS: 56511-19-4

Key Applications:

Electrochemical Systems

• Serves as a halide‑based ionic liquid component for studying ion transport, conductivity behavior, and electrode–electrolyte interfaces.
• Useful in evaluating iodide-containing electrolytes for redox‑active systems, including early‑stage dye‑sensitized solar cell research where iodide mobility and stability are key variables.
• Supports development of reference electrolytes for benchmarking cation–anion pairing effects in electrochemical devices.

Materials Science and Thin‑Film Processing

• Employed as a structure‑directing additive or templating agent in the formation of hybrid organic–inorganic materials.
• Investigated for its role in modulating crystallization, morphology, and surface charge in thin‑film deposition studies.
• Enables comparative studies on iodide vs. non‑halide pyrrolidinium salts in polymer matrices and composite materials.

Ion Transport and Solvation Studies

• Used in fundamental research on cation–anion interactions, solvation structure, and phase behavior of pyrrolidinium iodide systems.
• Supports NMR, Raman, and impedance spectroscopy investigations into ion pairing, viscosity effects, and temperature‑dependent transport.
• Provides a model system for understanding how alkyl chain length and halide identity influence ionic liquid physicochemical properties.

Catalysis and Reaction Media

• Functions as a non‑volatile, high‑ionic‑strength medium for halide‑assisted catalytic transformations.
• Suitable for exploring iodide‑driven nucleophilic substitution, phase‑transfer catalysis, and halide exchange reactions.
• Enables comparative studies of reaction kinetics in iodide‑rich ionic environments.

Analytical and Separation Science

• Utilized as an additive in chromatographic and electrophoretic method development to tune selectivity, retention, and ion–analyte interactions.
• Supports extraction and partitioning studies where iodide activity or halide‑specific interactions are variables of interest.

Reference Material for Structure–Property Mapping

• Provides a benchmark iodide salt for systematic comparison across pyrrolidinium cations with varying alkyl substituents.
• Useful in computational and experimental datasets mapping viscosity, conductivity, density, and thermal stability trends.
