Malachite green is a synthetic organic dye used industrially for coloring textiles, paper, and leather. It is a cationic triphenylmethane dye that appears as a green crystalline powder or liquid and is known for its intense colour. While also used in biology as a stain and in aquaculture as an antifungal and antiparasitic treatment, its use is regulated due to environmental concerns and potential toxicity.
