Description

Diethylzinc (DEZ) is a highly reactive organozinc compound with the molecular formula C₄H₁₀Zn and CAS number 557-20-0. It is a pyrophoric, colorless liquid that ignites spontaneously in air and reacts violently with water, making it essential to handle under inert conditions such as nitrogen or argon. Diethylzinc is widely utilized as a strong reducing agent, alkylating agent, and precursor in organic synthesis and materials science. Its high reactivity makes it invaluable for the formation of carbon-zinc bonds, polymerization catalysts, and semiconductor manufacturing (e.g., zinc sulfide thin films). Available in rigorously sealed ampoules or cylinders to ensure stability and safety, our high-purity Diethylzinc (≥98%) is ideal for research, industrial catalysis, and advanced material deposition processes.

Application

Diethylzinc is primarily used as a precursor in chemical vapor deposition (CVD) and atomic layer deposition (ALD) for producing zinc-containing semiconductor materials. It serves as a potent reducing agent in organic synthesis, enabling the formation of carbon-carbon bonds in specialized reactions. Additionally, DEZ is employed as a catalyst in polymerization processes, such as the production of polyolefins and elastomers.
