Application

Nickel(II) chloride hexahydrate can be used:
  • As a precursor to synthesize nickel(ll) complexes, such as nickel complexes of dithiocarbimates derived from sulfonamides.
  • To fabricate Ni-based composites for various applications such as photocatalysis.
  • As a catalyst for various organic reactions, for example, synthesis of tetra-substituted pyrroles and cleavage of tetrahydropyranyl (THP) and tert-butyldimethylsilyl (TBS) ethers.
  • As a starting material to prepare NiO nanoparticles.
