Ammonium oxalate, C2H8N2O4 (some times written as (NH4)2C2O4), is an oxalate salt with ammonium (sometimes as a monohydrate). It is a constituent of some types of kidney stone. Found also in guano.
Ammonium oxalate is an odorless, colorless
crystalline material or powder.
Ammonium oxalate is used as an analytical reagent and general reducing agent. It is commonly employed in soil chemical analysis to extract iron and aluminum from poorly-crystal line minerals.
ChEBI: An ammonium salt consisting of ammonium and oxalate ions in a 2:1 ratio.
Flammability and Explosibility

can emit toxic fumes of NH3 and NOx. See
also OXALATES.
It is used in chemical analysis and to
make blueprint paper, explosives; a rust-removal ingredient
in metal polishes.

Ammonium oxalate is a reducing agent
and also reacts as a base to neutralize acids and reacts with
oxidizers generating carbon dioxide. Incompatible with oxidizers (chlorates, hypochlorite solutions, nitrates, peroxides,
permanganates, perchlorates, chlorine, bromine, fluorine,
etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, epoxides.
