Frequently Asked Questions

What does the trace-metals specification mean?

This product is specified at ≥99.9999% 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 electronic grade mean?

electronic grade indicates that the material has been processed and tested for semiconductor and electronics manufacturing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.

How should this product be stored?

Store at room temperature, protected from light, 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 does PrimorTrace? Ultra mean?

PrimorTrace? Ultra 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? Ultra 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 107-98-2, the molecular formula is C4H10O2, and the molecular weight is 90.12 g/mol. InChIKey ARXJGSRGQADJSQ-UHFFFAOYSA-N.
