  With FeSO4 MGD, becomes a a useful component for the formation of the MGD2-Fe2+complex, which is an excellent nitric oxide (NO) spin-trapping reagent.

Acidic conditions should be avoided because dithiocarbamate tends to decompose forming toxic carbon disulfide. MGD and Fe(MGD)2 do not exhibit toxicity up to 8mmol/kg and 0.3mmol/kg, respectively.
