Brilliant Green (Malachite green G, Emerald green, Solid green JJO, Diamond green G, Aniline green, Benzaldehyde green, Fast green J) is a triarylmethane dye. Its formula is C27H34O4N2S. Its CAS number is 633-03-4. It is soluble in water and alcohol. Dye crystallizes in small, shiny, golden prisms.
Brilliant Green has been used to color silk and wool.
In Eastern Europe and Russia (and formerly the USSR) the dilute alcoholic solution of Brilliant Green is sold as a topical antiseptic, also known under a Latin name Viridis nitentis spirituosa and a Russian name зелёнка [zelyonka].
Brilliant Green is effective against gram-positive bacteria. The main advantage of Brilliant Green over the more common antiseptics such as Iodine is that it does not irritate mucous membranes. Therefore it is often used to treat infections of the eye, tongue sores and sinus infections. Brilliant green induces vomiting when swallowed and toxic when ingested.
