What is Bromine trifluoride

Product name:Bromine trifluoride
CAS
: 7787-71-5
Molecular Formula: BrF3
Molecular Weight: 136.90
Product description:A kind of inorganic compounds, colorless or light yellow liquid under atmospheric pressure. Exposed to the air can smoke, don't burn in the air. The chemical nature very lively, is a strong oxidizer.A good nonaqueous solvent, can dissolve many kinds of inorganic fluoride.One of the most widely used halogen compounds, it is a good solvent. Pure BrF3 liquid which have higher conductivity (> 8.01 x 10 Ω cm, 25 ℃), therefore many inorganic fluoride can dissolve well in BrF3 solvent, and ionization into corresponding ions. The stoichiometric compounds or elemental in three bromine fluoride reaction, can get the corresponding complexes.
