  • Applications

    Malachite Green is a triphenylmethane dye used as a colorant in textiles, paper, leather, and plastics, and as a pigment in coatings and inks. In microbiology and histology, it serves as a basic dye for staining organisms and cells, for example in the Schaeffer–Fulton endospore staining procedure. In aquaculture, it has been used to control bacterial and fungal infections in eggs and fry, subject to local regulatory requirements. It also appears in analytical and sensing applications as a colorant for analytical methods and optical sensors.
