Frequently Asked Questions

How is this product shipped?

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

What does the trace-metals specification mean?

This product is specified at ≥99.5% 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.

What does AR mean?

AR is a defined analytical purity tier suitable for general analytical and reagent applications. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. AR is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.

How should this product be stored?

Store in a cool place, desiccated. Keep the container tightly closed with desiccant — the material is moisture-sensitive.

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

The CAS Number is 7440-50-8, the molecular formula is Cu, and the molecular weight is 63.55 g/mol. InChIKey RYGMFSIKBFXOCR-UHFFFAOYSA-N.

What documentation is provided?

Available product documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and specification sheets, is shown in the product document area. Document availability and access follow the current site policy.
