-100 Mesh Powder
Storage & Sensitivity
Hygroscopic. Store under Nitrogen. Ambient temperatures.
Soluble in water. Insoluble in ethanol and carbon disulfide.


Sodium phosphate, tribasic is used in soaps, detergents, photographic developers, water softeners and boiler scale removers. It is used as a food additive, as cleaning agents, as a protein precipitant and an active ingredient in fluxes designed to deoxygenate nonferrous metals for casting. It is used to prepare chlorinated trisodium phosphate by reacting with sodium hypochlorite and used as a disinfectant and bleach. Further, it is used in dairy substitutes and to inhibit mold. In addition, it is employed in ceramic production. It is also used for the preservation of biologically active soil samples and fractionization of nucleotides.


Hygroscopic. Moisture sensitive. Incompatible with strong acids.
