1. What is Niobium(V) Bromide?

Niobium(V) Bromide (NbBr₅) is a niobium halide in which niobium has a +5 oxidation state. It is primarily used as a reactive niobium precursor for chemical synthesis and materials research.

2. What is NbBr₅ used for?

NbBr₅ is used in inorganic synthesis, organometallic chemistry, niobium compound preparation, materials research, thin-film research, and precursor chemistry.

3. What purity grades are available?

REG Metals can source 99%, 99.9%, and 99.99% purity grades, subject to availability and the required impurity specification.

4. Is Niobium(V) Bromide moisture sensitive?

Yes. NbBr₅ is sensitive to moisture and can react with atmospheric water. It should be stored and handled according to the supplier's SDS, typically using moisture-controlled or inert-atmosphere procedures.

5. Can particle size and packaging be customized?

Yes. Where applicable, particle size, packaging quantity, moisture limits, oxygen content, and trace-metal specifications can be customized according to the intended application.

6. Does REG Metals provide a Certificate of Analysis?

Yes. A Certificate of Analysis (COA) can be supplied documenting NbBr₅ purity, niobium and bromine content, moisture, oxygen, trace-metal impurities, physical characteristics, lot information, and other applicable specifications.
