General description

Hexamethylenetetramine (HMTA) is a water soluble, heterocyclic organic compound with a cage-like structure resembling adamantane. It is commonly used in treating urinary tract infection.

Application

Hexamethylenetetramine (HMTA) may be used as:
  • Raw material in the synthesis of blue emitting boron carbon oxynitride (BCNO) phosphors and Zinc oxide (ZnO) nanorods.
  • Catalyst in the synthesis of 2-amino-4H-pyran derivatives.
  • Surfactant in the synthesis of HMTA capped transition metals doped ZnS nanoparticles.
  • Precipitant and template in the synthesis of Ni(OH)2.
