Frequently Asked Questions

How should this product be stored?

Store at room temperature.

What does the trace-metals specification mean?

This product is specified at ≥99.99% 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 PrimorTrace? mean?

PrimorTrace? indicates that the chemical has been purified and tested specifically for use in trace and elemental analysis. Key specifications typically include controlled UV absorbance at common detection wavelengths, low non-volatile residue, controlled moisture content, and verified lot-to-lot consistency. PrimorTrace? is used for mobile phases, sample preparation and analytical standards in this workflow.

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

The CAS Number is 21651-19-4, the molecular formula is SnO, and the molecular weight is 134.71 g/mol. InChIKey QHGNHLZPVBIIPX-UHFFFAOYSA-N.
