Application

Sodium Hexametaphosphate (SHMP) can be used as:
  • A reagent for the oxidation of aldehydes to carboxylic acids in the presence of H2O2 as an oxidant.
  • A polymeric stabilizing and protecting agent in the synthesis of SHMP-stabilized gold nanoparticles (Au–SHMP) applicable in the development of biocompatible molecular probes.
  • A capping agent in the synthesis of sterically stabilized luminescent nanoparticles of manganese doped zinc sulfide (ZnS:Mn2+).
  • A stabilizing agent in the synthesis of barium sulfate nanoparticles by precipitation method.
