Diethyl dixanthogen disulfide is the organosulfur compound with the formula (C2H5OC(S)S)2.

It is one of the most common dixanthogen disulfides, compounds of the type (ROC(S)S)2 (R = alkyl).

The C-S-S-C dihedral angle is near 90°, as is common for acyclic disulfides.

[1] Diethylxanthogen reacts with aqueous base to regenerate the xanthate, at least partially.

[4] Diethylxanthogen arises by oxidation of xanthates during froth flotation.
