1-Allyl-3-methylimidazole bromide salt

1-Allyl-3-methylimidazole bromide salt, abbreviated as AMIMBr, is an organic compound with an imidazole ring with CAS number 31410-07-8.It consists of a methyl (-CH3) and an allyl (-CH2CH=CH2) substituting for the two nitrogen atoms on the imidazole ring, along with a bromide ion (Br-) as the counterion. This compound is liquid at room temperature, usually appears colourless to pale yellow, and has good solubility.

The melting point of AMIMBr is about 56°C , which means that at 56°C it changes from a liquid to a solid. As an ionic liquid, it is liquid at temperatures above its melting point, which makes it useful in many chemical reactions and industrial processes.

This compound has a wide range of applications in the fields of chemical synthesis, electrochemistry, green solvents and materials science. It can play an important role as a catalyst in organic synthesis reactions, as a nucleophilic reagent in a variety of organic reactions, such as nucleophilic substitution reactions, coupling reactions and cyclisation reactions, etc., and has high catalytic efficiency and selectivity .

AMIMBr also has good antimicrobial properties and can be used as an antimicrobial agent for controlling bacterial infections and is expected to solve the problem of antibiotic resistance, which is a common problem nowadays. In addition, it shows potential applications in the field of material science and surface modification, and can undergo ligand substitution reactions with metal surfaces and form stable surface complexes .
