一般描述

Myristyltrimethylammonium bromide (MTAB) is a quaternary ammonium compound that consists of a long-chain alkyl group and a positively charged quaternary ammonium group. It is commonly used as a cationic surfactant and as a phase transfer catalyst in various chemical reactions.

应用

Myristyltrimethylammonium bromide can be used as a cationic surfactant to:
  • Enhance the biomass harvesting and pigments extraction from the cyanobacterium Synechocystis sp. PCC 6803.
  • Facilitate the formation of mixed micelles with amitriptyline hydrochloride.
It can also be used as a capping agent for platinum nanoparticles (Pt NPs), which enhances their catalytic activity in the CO oxidation reaction.
