>> Product Introduce
Trioctylmethylammonium Bromide (T811-Br/TOMAB)
CAS 35675-80-0
Trioctylmethylammonium Bromide (CAS 35675-80-0) is a high-purity quaternary ammonium salt widely recognized as an exceptional phase transfer catalyst for organic synthesis and biphasic reactions. This white to off-white solid features a low melting point of 37-40°C, enabling easy handling and efficient transfer of reactive ions between aqueous and organic phases to significantly enhance reaction rates and yields in nucleophilic substitutions, oxidations, and reductions. Beyond catalysis, it serves as a versatile cationic surfactant and emulsifier for stabilizing oil-water mixtures, an effective extraction agent in hydrometallurgy for selective recovery of precious metals like platinum group elements, and a valuable additive in biochemical research for molecular purification and material science applications including corrosion inhibition.
>> Main Uses
