1-[(2-Methoxyethoxy)methyl]-1-methylpyrrolidin-1-ium Hexafluorophosphate, CAS 1420803-48-0, is an organic salt belonging to the ionic liquid family, built from a quaternary pyrrolidinium cation paired with a hexafluorophosphate anion. The pyrrolidinium cation in this compound carries an ether side chain, the (2-methoxyethoxy)methyl group, while the negative charge is carried by the PF₆⁻ anion. As an ionic liquid, this material belongs to the class of low-melting salts used in the laboratory as an alternative solvent, as an electrochemical medium, and as an electrolyte component that does not evaporate readily the way conventional organic solvents do.

The properties that make this material a preferred choice are its combination of very low vapour pressure, good thermal stability, and the wide electrochemical potential window characteristic of pyrrolidinium systems. The oligo-oxyethylene ether side chain serves to lower viscosity while increasing the flexibility of the cation and its ability to coordinate metal cations such as lithium, thereby assisting ion transport within the medium. The hexafluorophosphate anion contributes relative hydrophobicity along with adequate oxidative stability at high potentials, which is why this anion is commonly selected for demanding electrochemical environments.

Because it is practically non-volatile, an ionic liquid of this kind is well suited to work in Indonesian laboratories where solvent evaporation is a persistent concern under warm ambient conditions. It is typically found in university and institutional research groups working on electrochemistry, energy storage materials, and green solvent chemistry, as well as in specialty synthesis laboratories that require a reaction medium remaining stable over extended experimental periods without continuous replenishment.

Electrolyte formulation research: the wide potential window of the pyrrolidinium cation and the oxidative stability of the PF₆⁻ anion allow this salt to be evaluated as a non-volatile electrolyte component in laboratory-scale electrochemical cells.
Lithium ion transport studies: the oligo-oxyethylene ether side chain coordinates lithium cations and lowers viscosity, making this material useful for investigating ionic conductivity and ion mobility within ionic liquid media.
Alternative solvent chemistry: as a low-melting organic salt with negligible vapour pressure, it serves as a replacement medium for volatile organic solvents in reactions that require prolonged heating without solvent loss.
Electrochemical measurement media: its thermal stability and broad accessible potential range make it suitable as a supporting medium for voltammetry and other electroanalytical experiments requiring a stable, non-evaporating electrolyte environment.
Green chemistry and solvent screening: the combination of very low volatility and relative hydrophobicity from the hexafluorophosphate anion supports comparative studies of ionic liquids against conventional organic solvent systems in the laboratory.

Store this ionic liquid in a tightly sealed container in a cool, dry place away from direct sunlight and sources of heat, following the storage conditions indicated on the manufacturer's label. Suitable containers are the original supplier bottle or a chemically compatible glass vessel with a secure closure, since hexafluorophosphate salts are best protected from prolonged contact with atmospheric moisture. Handle the material in a well-ventilated area or fume hood, wear standard laboratory personal protective equipment including gloves, safety glasses, and a laboratory coat, and use clean, dry implements when transferring the material to avoid contamination. Keep the container clearly labelled and segregated from incompatible chemicals, and dispose of residues and contaminated materials in accordance with applicable laboratory chemical waste procedures.
