Cacodyl oxide is a chemical compound of the formula [(CH₃)₂As] ₂O. This organoarsenic compound is primarily of historical significance as it is sometimes considered to be the first organometallic compound synthesized in relatively pure form.

"Cadet's fuming liquid", which is composed of cacodyl and cacodyl oxide, was originally synthesized by heating sodium acetate with arsenic trioxide. It has a disagreeable odor and is toxic. It has been used as a denaturing and warning agent.Fact|date=September 2007
