Diethylzinc solution is widely used in the semiconductor industry as a precursor for zinc-containing thin films in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes. It plays a critical role in the production of advanced materials for electronics, such as zinc oxide layers, which are essential in solar cells, sensors, and transparent conductive coatings.

In organic synthesis, it serves as a strong reducing agent and alkylating agent, facilitating the formation of carbon-carbon bonds in complex molecular structures. This makes it valuable in the synthesis of pharmaceuticals, fine chemicals, and polymers.

Additionally, it is employed in the production of specialized catalysts for polymerization reactions, such as those involving olefins like ethylene and propylene, enhancing the efficiency and control of polymer manufacturing processes. Its reactivity and versatility make it a key component in various high-tech and industrial applications, including the synthesis of chemicals for pharmaceuticals and agriculture.
