  • Applications

    Brilliant Green cation (CAS 18198-35-1) is a cationic dye with practical applications mainly in microbiology and colorant manufacture. In microbiology, it is used as a dye component in selective culture media (for example Brilliant Green Agar) to aid in isolation and identification of certain enteric bacteria while inhibiting many Gram-positive organisms, enabling differential screening. It is also used as a staining reagent for microscopic observation of microorganisms. In the colorant and plastics industry, it is employed as a pigment/dye for inks, coatings, and plastics to yield a bright green color. In analytical chemistry, it can serve as a colorimetric indicator or dye in spectrophotometric methods to determine concentration or the presence of a sample. Its use is subject to local regulations and formulation limits.
