GENERAL DESCRIPTION & APPLICATIONS
Malachite green is a basic dye. Basic dyes are salts of the colored organic bases containing amino and imino groups and also combined with a colorless acid, such as hydrochloric or sulfuric. They are brilliant and most fluorescent among all synthetic dyes. Basic dyes are cationic which has positive electrical charge and are used for anionic fabrics which are negative-charge-bearing, such as wool, silk, nylon, and acrylics where bright dying is the prime consideration. Malachite green does not contain the mineral malachite; the name comes from the similarity of color. This chemical dye is primarily designed to be used as a dye for silk, leather, and paper. Malachite green in dilute solution is widely used medicinally as a local antiseptic. It is effective against parasites, fungal infections and gram-positive bacteria. In combination with formalin as a synergist, malachite green is a common antiseptic agent against the fungus Saprolegnia, a typical water mold that kills fish eggs and young fry. But the use has been banned in many countries due to its suspect of carcinogenicity. Malachite green is used as a biological stain as a counterstain against fuchsin which stains gram-positive and gram-negative bacteria reddish colors and safranin which stains nuclei red. Malachite green stain background to the surrounding tissue blue-green. Malachite green is used as a pH Indicator between pH 0.2 (green) - 1.8 (blue-green)

TRIPHENYLMETHANE DYES
Triphenylmethane is the basic skeleton of many dyes. Trityl anion stabilized by extensive delocalization over three phenyl rings absorbs the visible region of the spectrum and originates brilliant and fluorescent red to violet colors.
