Used primarily as a precursor in organometallic chemistry and materials science, especially in the synthesis of tellurium-containing compounds. It serves as a source of tellurium in the preparation of metal tellurides and semiconductor materials, which are important in optoelectronic devices and infrared detectors. Its volatility and reactivity make it suitable for vapor deposition techniques, such as chemical vapor deposition (CVD), where controlled thin films of tellurium-based materials are required. Also employed in research settings to introduce tellurium into complex organic and inorganic frameworks, enabling the study of novel chalcogenide chemistry.
