General description

Myristyltrimethylammonium bromide is a cationic/zwitterionic type of surfactant.

Application

Myristyltrimethylammonium has been used in a study to assess a surfactant-controlled synthetic method to obtain a nanophase of mesoporous ceria-zirconia solid solution containing cationic defects in the crystalline structure. It has also been used in a study to determine the low molecular weight of organic acids in soils and plants by capillary zone electrophoresis.
