Basic Violet 2, also known as New Fuchsin (CI 42520), is a synthetic basic dye of the triamino triphenylmethane dye family. It is commonly used in the laboratory of microbiology, histology, pathology, and life sciences for staining of cells, tissues, and microorganisms for microscopic analysis.
It has excellent staining performance and strong color intensity that gives a bright red to magenta color, which provides good contrast in various biological staining techniques. It is commonly used in Ziehl-Neelsen staining, Gram staining, and Schiff reagent-based techniques employed in research, diagnostic, and educational laboratories.
