Praseodymium bromide is an inorganic compound with the chemical formula Pr(BrO₃)₃. It is soluble in water and can form the dihydrate, tetrahydrate^[1] and nonahydrate. The nonahydrate melts in its own crystal water at 56.5 °C and completely loses its crystal water at 130 °C.^[2] It can be produced by the reaction of barium bromate and praseodymium sulfate.^[3]
