About Copper chromate

Copper chromate is a transition metal compound carrying the CAS registry number 13548-42-0. The compound has the formula CrCuO4, corresponding to a molecular weight of 179.54 g/mol. Systematically, it is named copper dioxido(dioxo)chromium. Alternative names: Cupric chromate(VI) and copper dioxido-dioxo-chromium.

The product is provided as a solid. Key physical data: a melting point of 498 °C and a density of 4.77 g/mL at 25 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include materials research and chemical synthesis. Typical end-use sectors are academic and industrial research.

Standard pack sizes are 100 g, 500 g, 5 kg and 25 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
