Ammonium oxalate is a

monohydrate
([NH4]2C2O4·H2O). It is a colorless or white salt under standard conditions and is odorless and non-volatile. It occurs in many plants and vegetables.

Vertebrate

It is produced in the body of

kidney stone.[3][4] It is also found in guano
.

Mineralogy

Oxammite is a natural mineral form of ammonium oxalate. This mineral is extremely rare. It is an organic mineral derived from guano.[5]

Chemistry

Ammonium oxalate is used as an analytical reagent and general reducing agent.[2] It and other oxalates are used as anticoagulants, to preserve blood outside the body.[citation needed]

Earth sciences

Acid ammonium oxalate (ammonium oxalate acidified to pH 3 with oxalic acid) is commonly employed in soil chemical analysis to extract iron and aluminium from poorly-crystalline minerals (such as ferrihydrite), iron(II)-bearing minerals (such as magnetite) and organic matter.[6][page needed]
