FAQs

Question: Which compound and pack size are supplied?

Answer:Copper(II) oxide, CuO, nominal 97% purity, supplied as 500 g powder in a plastic bottle.

Question: Is this the same as copper(I) oxide?

Answer:No. Copper(II) oxide contains copper in the +2 oxidation state and must not be substituted for copper(I) oxide.

Question: Is it suitable as a certified elemental calibration standard?

Answer:No certified elemental concentration is implied; use a designated traceable standard for quantitative instrumental calibration.

Application Note

Thermo Scientific Chemicals copper(II) oxide is a black inorganic copper oxide powder used as a laboratory reagent and starting material in chemical synthesis and materials investigations. The 500 g plastic-bottle configuration provides nominal 97% purity and has the molecular formula CuO, with a formula mass of 79.55 g/mol. Laboratory applications include preparation of copper-containing compounds, investigation of heterogeneous solid-phase chemistry and evaluation of metal-oxide materials. It is distinct from copper(I) oxide, Cu₂O, which has different oxidation state, properties and reactions. Weigh the powder with suitable dust-control precautions, select compatible reaction vessels and verify solvent and acid compatibility for the method. The analytical grade and impurity profile are not equivalent to certified elemental standards for trace-metal calibration. Review the safety data sheet before handling, prevent environmental release, and use the lot-specific certificate when assay or impurity limits are critical to an experiment.
