Malachite green oxalate is a salt form of malachite green, a triphenylmethane dye known for its intense green color. This compound has been used historically as a dye for silk, leather, and paper, as well as a biological stain in microbiology. In aquaculture, it has been employed as an antifungal and antiparasitic agent. However, due to concerns over its toxicity and potential carcinogenic properties, its use has been restricted or banned in many countries.
