The dye Ethyl Green (C.I. 42590; C27H35BrClN3) is a triarylmethane dye.[1][2][3] It is soluble in water.[3]

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.[3]

Methyl green is a closely related dye used as a stain in histology.[3] Ethyl green is also used as a histological dye.[1]
