Sodium Oxalate
American Elements
Sodium Oxalate 99%
Odor: characteristic
Use: Sodium Oxalate is highly insoluble in water and converts to the oxide when heated (calcined). Sodium Oxalate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards.
