Description

Dimethylcadmium (CAS: 506-82-1) is a highly reactive organometallic compound with the molecular formula C₂H₆Cd. This volatile, pyrophoric liquid is widely utilized in advanced chemical synthesis and material science applications due to its strong alkylating properties. As a cadmium(2+) derivative, it serves as a critical precursor for the deposition of cadmium-containing thin films in semiconductor and photovoltaic research. Dimethylcadmium must be handled with extreme caution under inert atmospheres due to its air- and moisture-sensitive nature. Suitable for vapor phase epitaxy (VPE) and metalorganic chemical vapor deposition (MOCVD) processes. Purity levels available upon request for specialized research applications.

Application

Dimethylcadmium is primarily employed as a precursor in the production of cadmium-based semiconductor materials through MOCVD processes. Researchers utilize this compound for the synthesis of quantum dots and II-VI compound semiconductors with precise stoichiometric control. Its high volatility makes it suitable for vapor-phase deposition techniques in optoelectronic device fabrication. In organic synthesis, it serves as a potent methylating agent for specialized transformations.
