1-Butylpyridinium bromide(CAS: 874-80-6)

1-Butylpyridinium bromide is a quaternary ammonium salt with the chemical formula C10H17BrN. It is a colorless to pale yellow liquid with a characteristic odor, commonly used as a phase transfer catalyst. Its properties include high solubility in organic solvents and a moderate melting point, making it suitable for various chemical applications.

1-Butylpyridinium bromide is primarily used as a phase transfer catalyst in organic synthesis, aiding in reactions such as esterifications and oxidations. It is also employed in pharmaceutical and industrial processes, and in research for its ability to facilitate ion transfer between aqueous and organic phases. Its versatility makes it a valuable reagent in chemical manufacturing.

1-Butylpyridinium bromide is generally considered safe when handled properly, but it should be treated with caution. It may cause skin and eye irritation, so protective gloves, goggles, and proper ventilation are recommended. Safety standards advise against ingestion and prolonged exposure, and it is classified as a substance with potential toxicity in certain conditions.

1-Butylpyridinium bromide should be stored in a cool, dry, and well-ventilated area, away from light. It is best kept in a sealed container made of glass or high-density polyethylene (HDPE) to prevent contamination and maintain stability. Storage conditions should be below 25°C to avoid degradation and ensure optimal performance.
