Digold trioxide (Cat No.: M047929) is a rare and unstable compound composed of gold in the +3 oxidation state and oxygen, typically appearing as a dark reddish-brown solid. It decomposes upon heating, releasing oxygen and forming metallic gold. Due to gold’s reluctance to form stable oxides, Au₂O₃ is mostly of academic interest in inorganic and materials chemistry. It may be explored for its oxidizing properties, potential use in catalysis, and its relevance in the study of gold oxidation states and coordination environments.
