The Ammonium oxalate, with the CAS registry number 1113-38-8, is also known as Diammonium ethanedioate. Its EINECS registry number is 214-202-3. This chemical's molecular formula is C₂H₈N₂O₄ and molecular weight is 124.10. What's more, its IUPAC name is called Diazanium oxalate. It should be stored in a cool, dry and well-ventilated place. This chemical is an oxalate salt with ammonia. It is a constituent of some types of kidney stone. Found also in guano. Firstly, take oxalic acid dissolved in water, add it into the ammonia solution and keep stirring the solution rapidly while it is cooled to 25 °C, then filter out the crystals, and dred at room temperature to get Ammonium oxalate. This chemical can be used for the analysis of reagent and has been used in organic synthesis as intermediate.
