Uranium monophosphide is a compound of uranium and phosphorus, synthesized from heating metal uranium and white phosphorus:

4 U + P 4 ⟶ 4 UP {\displaystyle {\ce {4U + P4->4UP}}} It is a potential nuclear fuel.

In air, a thin glassy surface layer protects the compound from oxidation; over the course of months after synthesis, this layer develops a metallic sheen.
