1-Hexyl-3-methyl-1H-imidazol-3-ium hexafluorophosphate(CAS: 304680-35-1)

1-Hexyl-3-methyl-1H-imidazol-3-ium hexafluorophosphate is a quaternary ammonium salt with a molecular structure consisting of an imidazole ring substituted with a hexyl and a methyl group, and a hexafluorophosphate anion. It is a colorless or white crystalline solid with good solubility in common organic solvents.

This compound is primarily used as a cathode additive in lithium-ion batteries, where it enhances battery performance and stability. It also finds applications in polymer chemistry as a crosslinking agent and in surface treatments for its antimicrobial properties.

While generally safe for use, this compound should be handled with care. It is non-toxic by inhalation, ingestion, or skin contact, but prolonged exposure to its dust or fumes may cause irritation. Proper personal protective equipment, such as gloves and safety glasses, should be worn during handling and storage.

Store the compound in a cool, dry place, away from direct sunlight and heat sources. Keep the container tightly sealed to prevent moisture absorption. Avoid contact with incompatible materials such as acids, which may cause a hazardous reaction. Store in a well-ventilated area and avoid inhaling the dust or fumes.
