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.[1]
  • Methyl methacryalate (MMA) by oxidative dehydrogenation of methyl iso-butarate (MIB).[2]

It can be also used in the synthesis of carbon coated lithium iron phosphate (LiFePO4) as the cathode material for lithium ion batteries.[3][4][5] It is also used as a key ingredient in preparing phosphate glass fibers.[6]
