Frequently Asked Questions

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 Ultra dry mean?

Ultra dry indicates that the material has been processed and tested for moisture-sensitive chemistry. 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.

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.

How should this product be stored?

Store at room temperature, protected from light, desiccated. Keep the container tightly closed with desiccant — the material is moisture-sensitive.

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 7789-40-4, the molecular formula is TlBr, and the molecular weight is 284.29 g/mol. InChIKey PGAPATLGJSQQBU-UHFFFAOYSA-M.
