Frequently Asked Questions

What does the trace-metals specification mean?

This product is specified at ≥99.98% 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 analytical standard mean?

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

How should this product be stored?

Store at room temperature under argon. It is supplied under an argon blanket; reseal under inert gas after each use.

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 7447-40-7, the molecular formula is KCl, and the molecular weight is 74.55 g/mol. InChIKey WCUXLLCKKVVCTQ-UHFFFAOYSA-M.

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.
