Description

Tantalum(V) chloride is used in the preparation of catalyst for the polycyclotrimerizations of alkenediynes, chloro-aryloxide compounds and for the plasma-enhanced atomic layer deposition of tantalum nitride films. It acts as a starting material for new edge-bridged octahedral M₆ cluster compounds. It is involved in the preparation of tantalum(V) oxychloride, tantalum pentoxide. It is electrophilic and behaves like a Friedel-Crafts type catalyst, similar to aluminum(III) chloride.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
