Application: Ethyl violet is a cationic triarylmethane dye that is the ethyl homolog of crystal violet. It is a general histological and pathological stain. Ethyl violet has been used to stain pancreatic tissue and elastin, in the detection of gram negative bacteria, and as a reagent for the extractive-spectrophotome​tric determination of anionic surfactants. Ethyl violet induces mitochondrial permeability. It has been used in the extraction and spectrophotometric determination of copper. Along with the anionic dye zincon, ethyl violet is used in counterion dye of proteins in SDS-polyacrylamide gel electrophoresis.
