The dye Ethyl Green ( C.I. 42590; C₂₇H₃₅N₃ClBr is a triarylmethane dye. It is soluble in water.

Its CAS number is [7114-03-6] and its SMILES structure is C/[N+](C)=C (C=C3)/C=C\C3=C (C2=CC=C([N+](C) (CC)C)C=C2)/C1=C C=C(N(C)C)C=C1.

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. Methyl green and ethyl green are very similar and probably interchangeable.
