CAS 4519-28-2

Phosphonium, tetramethyl-, bromide

Description:

Tetramethylphosphonium bromide (TMPB) is a quaternary ammonium salt characterized by its phosphonium cation, which consists of a phosphorus atom bonded to four methyl groups and a bromide anion. This compound is typically a white crystalline solid that is soluble in polar solvents such as water and alcohols, making it useful in various chemical applications. TMPB is known for its role as a phase transfer catalyst, facilitating the transfer of ions or molecules between immiscible phases, which is particularly valuable in organic synthesis. Additionally, it can serve as a source of the tetramethylphosphonium ion in various reactions, including nucleophilic substitutions. The compound is relatively stable under standard conditions but should be handled with care due to its potential toxicity and irritant properties. Its applications extend to fields such as organic chemistry, materials science, and biochemistry, where it aids in enhancing reaction efficiencies and yields.
