Tin oxalate is used as a catalyst in the production of organic esters and plasticizers.
[4]
It is used for dyeing and printing fabrics.
The compound is also used in stannous oral care compositions.
Few studies have reported on the use of tin(II) oxalate as an anode material for rechargeable
lithium batteries .
