Tetra Methyl Ammonium Bromide

Product Details:


Product Description

With the chemical formula (CH3)4NBr, tetramethylammonium bromide (TMABr), also referred to as tetramethylammonium bromide, is a quaternary ammonium salt. It is a crystalline powder that is white or off-white in colour and soluble in polar organic solvents as well as water.

In organic synthesis, TMABr is frequently utilised as a phase transfer catalyst, especially in reactions involving anions or nucleophiles that are insolubility in organic solvents. It can make it easier for these species to move between immiscible phases, which will speed up reactions.

In the process of creating nanoparticles, TMABr can also be utilised as a surfactant to help stabilise and regulate the size of the particles. It has been researched for its possible use in both the generation of biofuels and the removal of heavy metals from contaminated water.

The improper handling of TMABr can have hazardous effects similar to those of other quaternary ammonium compounds. When dealing with TMABr, it's crucial to adhere to safety precautions and use protective gear because it can irritate the skin, eyes, and respiratory system when consumed or inhaled.
