The pure form of Fomaxium is in the form of flake-like white crystals. It is highly soluble in water. The crystals obtained by recrystallization method contain 2.5 molecules of crystalline water. When heated to 115°C, 2 molecules of crystalline water are lost, and when heated to 130°C, all the crystalline water is lost. The industrial intermediate is a 15% aqueous solution, which is a transparent liquid of light yellow or grass green color. Its relative density is 1.06 and pH is 9 to 11. Fomaxium can also be used as a soil disinfectant.
