Tetrapropylammonium Bromide (TPABr), identified by its CAS number 1941-30-6, is a prominent quaternary ammonium salt widely utilized across various industrial and research applications. This white to almost white crystalline powder has a molecular formula of C12H28BrN and a molecular weight of approximately 266.26. Its distinctive chemical structure, featuring four propyl groups attached to a central nitrogen atom, contributes to its unique properties and versatility in organic synthesis and material science.

Known for its high purity, typically exceeding 99.0%, TPABr exhibits several key physical and chemical characteristics. It has a melting point ranging from 266 to 272 °C and is highly soluble in water, forming clear aqueous solutions with a pH of 5-7. Being hygroscopic, it readily absorbs moisture from the air, necessitating proper storage conditions to maintain its integrity. Its stability is generally good, though it is incompatible with strong oxidizing agents. These properties make it a valuable compound for a multitude of specialized chemical processes.

One of the primary applications of Tetrapropylammonium Bromide is its function as a molecular sieve template. In this role, it plays a crucial part in the synthesis of zeolites and other porous materials, guiding the formation of specific pore structures essential for adsorption, catalysis, and separation technologies. Its templating ability allows for the creation of advanced materials with tailored properties, driving innovation in fields such as petrochemicals and environmental science.

Furthermore, TPABr serves as an effective phase transfer catalyst in organic synthetic chemistry. It facilitates reactions between immiscible phases, significantly enhancing reaction rates and yields. Its catalytic prowess extends to various complex transformations, including halogen replacement reactions, redox reactions, N-alkylation, and the generation of dichlorocarbene. Beyond its role as a catalyst, TPABr is also employed as a surfactant, detergent, adsorption agent, and oil displacing agent, underscoring its broad utility in industrial formulations. It can act as a polymer polymerization curing accelerator, an organic electrolyte for the organic industry, and an important chemical agent in oilfield operations. Additionally, it finds use as a phase change cold storage material and a high-performance liquid chromatography (HPLC) reagent.

Proper handling and storage are crucial for preserving the quality and efficacy of Tetrapropylammonium Bromide. It should be stored in a cool, dry, and well-ventilated location, protected from direct light and moisture due to its hygroscopic nature. Safety precautions, such as wearing appropriate personal protective equipment, should always be observed when handling this chemical. While generally safe with proper handling, it is classified as an irritant to skin and eyes, and appropriate first aid measures should be followed if exposure occurs.
