Description

Hafnium(IV) chloride is used as a precursor for catalyst involved in the Ziegler-Natta polymerization of propylene. It is an effective Lewis acid for various applications in organic synthesis viz alkylation of ferrocene. Further, it increases the rate and control of 1,3-dipolar cycloadditions. It is also used to prepare hafnium dioxide and hafnium silicate, which is used as high-k-dielectrics in the production of integrated circuits. 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. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
