Malachite Green
Malachite Green is a synthetic organic compound classified as a triarylmethane dye. It appears as a green crystalline powder with a brilliant metallic sheen and is highly soluble in water and alcohol. While originally developed as a textile dye, Malachite Green is widely used in aquaculture, microbiology, and histology due to its antifungal, antibacterial, and staining properties. It is typically available in two forms: the oxalate and hydrochloride salts. Although effective in many industrial and biological applications, its use in food and veterinary contexts is restricted or banned in several countries due to toxicity concerns.
