Perguntas frequentes

What does the trace-metals specification mean?

This product is specified at ≥99.998% 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 is classified as dangerous goods and ships via FedEx DG Service. Ground and other economy services are not available, and delivery to some destinations or address types may be restricted.

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

The CAS Number is 7440-21-3, the molecular formula is Si, and the molecular weight is 28.09 g/mol. InChIKey XUIMIQQOPSSXEZ-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.
