Application

Iron(III) phosphate dihydrate (FePO4 x 2H2O) can be used as a catalyst in the synthesis of:
  • 3,4-dihydropyrimidin-2(1H)-ones and thiones by reacting with aldehydes, β-ketoesters and urea/thiourea via one pot-three component Biginelli reaction.
  • Methyl methacryalate (MMA) by oxidative dehydrogenation of methyl iso-butarate (MIB).

It can be also used in the synthesis of carbon coated lithium iron phosphate (LiFePO4) as the cathode material for lithium ion batteries. It is also used as a key ingredient in preparing phosphate glass fibers.
