Domande frequenti

What does the trace-metals specification mean?

This product is specified at ≥99.9% on a trace-metals basis. That figure describes metallic impurity content rather than overall chemical assay, so it is the relevant specification for ICP-MS, semiconductor and battery applications. Lot-specific values are stated on the Certificate of Analysis.

How should this product be stored?

Store at 2–8 °C under argon. It is supplied under an argon blanket; reseal under inert gas after each use.

How is this product shipped?

This product ships chilled on wet ice. Unpack on arrival and transfer it to the storage condition stated above.

What are the CAS number, molecular formula and molecular weight?

The CAS Number is 12030-49-8, the molecular formula is IrO2, and the molecular weight is 224.22 g/mol. InChIKey HTXDPTMKBJXEOW-UHFFFAOYSA-N.
