Application

Hexadecyltrimethylammonium hydroxide solution is a surfactant used in:
  • Synthesis of microporous and mesoporous aluminosilicate molecular sieves such as MCM-41 and MCM-48.
  • Hydrothermal preparation of manganese dioxide (MnO2) nanoflower.
  • Synthesis of cetyltrimethylammonium hydroperoxide, a reagent used for promoting phosphate ester hydrolysis.
