Dithiooxamide, or rubeanic acid, is an organic compound that shares a chemical resemblance to oxamide but contains sulfur. Its properties make it useful as a chelating agent, particularly in the identification and measurement of copper. Moreover, dithiooxamide has found application as a foundational component in the production of cyclen through synthesis.
