Description

Dimethylzinc (C₂H₆Zn) is a highly reactive organozinc compound with the CAS number 544-97-8. It is a pyrophoric, colorless liquid that is widely used in organic synthesis and semiconductor manufacturing. As a powerful methylating agent, Dimethylzinc is essential in the deposition of zinc-containing thin films via Metal-Organic Chemical Vapor Deposition (MOCVD) and Atomic Layer Deposition (ALD). This ultra-high-purity reagent is packaged under inert gas to ensure stability and is ideal for advanced research in materials science, nanotechnology, and optoelectronics. Handle with extreme caution in a controlled environment due to its air- and moisture-sensitive nature.

Application

Dimethylzinc is primarily used in the semiconductor industry for the deposition of zinc-based thin films in MOCVD and ALD processes. It serves as a key precursor for the synthesis of II-VI compound semiconductors, such as zinc sulfide (ZnS) and zinc selenide (ZnSe). Researchers also employ it as a methylating agent in organic synthesis for the formation of carbon-carbon bonds. Its high reactivity makes it valuable in the production of advanced optoelectronic materials.
