1-Ethylpyridinium Bromide is offered in high purity, suitable for both industrial and pharmaceutical synthesis, and is available in stock for immediate supply. Designated by CAS Number 85756-65-6, this compound serves as a versatile reagent in the electrochemical synthesis of fine chemicals, enabling efficient transformations under controlled flow chemistry and continuous manufacturing settings.
Chemically, 1-Ethylpyridinium Bromide is characterized by the molecular formula C7H10BrN and has a molecular weight of 188.07 g/mol. Structurally, it belongs to the class of pyridinium salts, incorporating the ethyl-functionalized pyridinium cation paired with a bromide counterion. As a quaternary ammonium salt, its enhanced ionic conductivity and thermal stability make it particularly well-suited for use as an electrolyte or mediating agent in electrochemical processes. The compound exhibits a density of 1.35 g/cm³ and melts at 161°C, which facilitates its handling in various synthesis protocols. Its logP value of -1.3 indicates hydrophilicity, suggesting favorable solubility in polar solvents and minimizing volatility concerns, as corroborated by its non-volatile physical state and lack of a meaningful boiling or flash point under standard conditions.
This product is supplied with an assay purity exceeding 99% and contains less than 0.2% water by content, ensuring suitability for demanding synthetic applications where moisture sensitivity or purity constraints are critical. It presents as a white to off-white crystalline solid, which is stable under recommended storage conditions.
In the context of electrochemical synthesis, 1-Ethylpyridinium Bromide is primarily valued as a supporting electrolyte and phase transfer catalyst, facilitating the efficient mediation of electron transfer reactions. Its application extends to the production of specialty intermediates and fine chemicals, often driving improvements in selectivity and energy efficiency during anodic and cathodic processes. It is frequently integrated into continuous flow electrochemical reactors, yielding enhanced process control and scalability. Beyond electrochemical synthesis, this compound is also employed in the generation of N-alkylpyridinium salts for ionic liquid precursor development, is used as a template in advanced materials synthesis, and acts as a phase-transfer reagent for polar organometallic transformations. Its role in facilitating greener chemistry practices in both pharmaceutical and agrochemical manufacturing underscores its growing industrial importance.
For large-scale operations, 1-Ethylpyridinium Bromide is supplied in 25kg high-density polyethylene drums, each filled under nitrogen-purged headspace to preserve stability and prevent moisture ingress. The product should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible reagents. Under these conditions, its shelf life exceeds 24 months. Full Certificate of Analysis (COA) documentation is provided with every batch to meet quality assurance and regulatory requirements.
