Niobium Chloride| NbCl5| CAS 10026-12-7| Facoty Supply| High Purity 99.9%

Short Description:

Niobium(V) chloride, also known as niobium pentachloride, is a yellow crystalline solid. It hydrolyzes in air, and samples are often contaminated with small amounts of NbOCl₃. It is often used as a precursor to other compounds of niobium. NbCl₅ may be purified by sublimation.

Specification

Niobium chloride NbCl5 CAS 10026-12-7

Application

Niobium chloride NbCl5 CAS 10026-12-7

Used to form mixed chloro-aryloxide compounds, such as [Nb(OC6H3-2,6-i-Pr2)2Cl3]2, which form pyridine or phosphine adducts with a distorted six-coordinate geometry.

Used as Lewis acid catalyst in organic synthesis.

Niobium(V) chloride is the precursor in the preparation of pure niobium, and ferroniobium. It is used as a Lewis acid catalyst in organic synthesis in activating alkenes in the carbonyl-ene reaction and the Diels-Alder reaction.
