Used primarily in research and specialized chemical synthesis, this compound serves as a reagent in the preparation of organotellurium compounds, which have applications in organic electronics and semiconductor materials. It is also employed in the study of tellurium chemistry due to its ability to act as a chlorinating and oxidizing agent. Its reactivity makes it useful in the transformation of various organic substrates, particularly in the development of novel catalysts and functional materials. Due to its sensitivity to moisture and air, handling requires inert conditions, limiting its use to controlled laboratory environments.
