Ethyl Green

The dye Ethyl Green (C.I. 42590; C27H35BrClN3) is a triarylmethane dye. It is soluble in water.

Ethyl green is made of crystal violet by adding an ethyl group; crystal violet is therefore a possible contaminant.

Methyl green is a closely related dye used as a stain in histology. Ethyl green is also used as a histological dye.
