Understanding the fundamental chemical properties and synthesis pathways of specialized compounds is crucial for researchers and product formulators. 1-Butylpyridinium Bromide, identified by CAS number 874-80-6, is a heterocyclic organic compound that has found increasing utility in various scientific and industrial applications. This article aims to provide a comprehensive overview of its key chemical characteristics and common synthesis methods, empowering professionals to make informed decisions when looking to buy or use this chemical intermediate.

At its core, 1-Butylpyridinium Bromide is a quaternary ammonium salt derived from pyridine. Its molecular formula is C9H14BrN, and it has a molecular weight of approximately 216.12 g/mol. Typically presented as a white to off-white crystalline powder or crystals, its physical appearance is an initial indicator of quality. When considering its chemical behavior, it's important to note its hygroscopic nature, meaning it can absorb moisture from the air. Therefore, proper storage, often in an inert atmosphere and at room temperature, is recommended to maintain its integrity and purity, typically maintained at ≥98.0% by HPLC.

The synthesis of 1-Butylpyridinium Bromide usually involves a direct quaternization reaction. The most common method is the reaction between pyridine and 1-bromobutane. This nucleophilic substitution reaction, where the nitrogen atom of pyridine attacks the electrophilic carbon atom of the butyl halide, leads to the formation of the pyridinium cation with bromide as the counterion. The reaction conditions, such as temperature, solvent, and reaction time, are critical for optimizing yield and purity. Manufacturers often refine these processes to ensure the product meets high standards, making it suitable for demanding applications.

The properties of 1-Butylpyridinium Bromide make it a valuable intermediate. Its ionic nature means it can function as a component in ionic liquids, which are salts that are liquid at or near room temperature. These ionic liquids possess a unique set of properties, including negligible vapor pressure, high thermal stability, and excellent solvency, making them candidates for 'green' chemical processes, catalysis, and electrochemistry. Researchers interested in developing novel ionic liquids can readily buy this precursor.

Beyond its role in ionic liquids, this compound is also employed in organic synthesis as a building block or catalyst. Its availability from reputable chemical manufacturers, particularly those based in China, ensures that researchers and industrial chemists have access to a reliable source of this important chemical. When procuring, attention to detail regarding batch-to-batch consistency and supplier technical support is essential.

In summary, 1-Butylpyridinium Bromide (CAS 874-80-6) is a well-defined heterocyclic compound with important applications stemming from its chemical structure and properties. Understanding its synthesis and handling requirements is key to its successful application in research and industry. For those looking to buy this versatile chemical, partnering with experienced manufacturers and suppliers guarantees the quality and reliability needed for advanced chemical projects.
