malachite green

▪ drug and dye
also called  aniline green,  benzaldehyde green , or  china green 

      triphenylmethane dye used medicinally in dilute solution as a local antiseptic. Malachite green is effective against fungi and gram-positive bacteria. In the fish-breeding industry it has been used to control the fungus Saprolegnia, a water mold that kills the eggs and young fry.

      Malachite green also is used as a direct dye for silk, wool, jute, and leather and to dye cotton that has been mordanted with tannin. Prepared from benzaldehyde and dimethylaniline, the dye occurs as lustrous green crystals soluble in water and in alcohol. For malachite green G, see brilliant green.
