Description

Dimethylzinc (CAS NO 544-97-8) is a highly reactive organometallic compound that serves as a fundamental precursor in advanced materials synthesis. Its primary value lies in its role as an efficient methyl group transfer agent and a volatile source of zinc for vapor-phase deposition processes. This product is essential for manufacturers and researchers in the semiconductor, photovoltaic, and specialty chemical industries seeking to create high-purity thin films and complex organic-zinc compounds.

Application

• Metal-Organic Chemical Vapor Deposition (MOCVD): A key precursor for depositing high-purity zinc-containing thin films, such as zinc oxide (ZnO) and zinc selenide (ZnSe), used in optoelectronic devices.
• Semiconductor Manufacturing: Employed in the production of II-VI compound semiconductors for applications in LEDs, laser diodes, and solar cells.
• Organic Synthesis: Acts as a powerful methylating agent and nucleophile in the synthesis of complex organic molecules and pharmaceuticals under anhydrous conditions.
• Polymerization Catalyst: Used as an initiator or co-catalyst in Ziegler-Natta type polymerizations for producing specialized polyolefins.
• Research & Development: A critical reagent in academic and industrial labs for developing new materials and catalytic processes.
• Nanomaterial Fabrication: Serves as a zinc source for the controlled synthesis of zinc-based nanoparticles and quantum dots.

Quality Control

Our Dimethylzinc is manufactured and handled under stringent, moisture-free conditions to ensure the highest purity and consistency. Each batch is analyzed using advanced techniques including GC, NMR, and Karl Fischer titration to verify critical parameters such as assay, metal impurities, and moisture content. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing the product's conformance to agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric and highly volatile nature, this product must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area, away from heat, ignition sources, and oxidizing agents. Recommended storage temperature is between 2°C and 8°C. The container must be kept sealed and handled only with appropriate equipment in a dedicated, controlled environment.
