Domande frequenti

What does the trace-metals specification mean?

This product is specified at ≥99.95% 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 room temperature.

How is this product shipped?

This product ships under standard ambient conditions. No temperature-controlled packaging is required.

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

The CAS Number is 7440-47-3, the molecular formula is Cr, and the molecular weight is 52 g/mol. InChIKey VYZAMTAEIAYCRO-UHFFFAOYSA-N.
