Dimethylzinc - DMZn

AkzoNobel offers the highest purity dimethylzinc under the product name of DMZn SSG (Select Semiconductor Grade). DMZn SSG is used as a high quality zinc precursor for the deposition of compound semiconductors which are used in applications such as light emitting diodes, laser diodes, high performance transistors and high efficiency solar cells.


CAS Number: 544-97-8
Appearance: clear, colorless liquid
Density, 28°C: 1.313 g/ml
Melting point: -29°C 
Boiling point: 44°C
Stability to air: ignites upon exposure
Stability to water: reacts violently, may ignite upon contact
Solubility: soluble in aromatic, saturated aliphatic and cycloaliphatic hydrocarbons

Please refer to the Product Data Sheet of DMZn SSG for more information or contact us for detailed specifications. 

Dimethylzinc is stable when stored under a dry, inert atmosphere and away from heat. The product may undergo exothermic decomposition with gas evolution at elevated temperatures. 

Packaging and transport
Containers are fabricated from stainless steel with an electropolished internal finish and are equipped with dip tube for top discharge and diaphragm valves. The diaphragm valves are equipped with metal gasket face seal connections such as Swagelock® VCR®.

Safety and handling 
Dimethylzinc ignites upon exposure to air and reacts violently with water. Water must be scrupulously removed from process equipment prior to putting it into metal alkyls service. Failure to do so may result in an explosion. Products of complete combustion of dimethylzinc are zinc oxide, carbon dioxide and water. Dimethylzinc severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling DMZn SSG. 

Please refer to the Material Safety Data Sheet (MSDS) for further information on the safe storage, use and handling of DMZn SSG. This information should be thoroughly reviewed prior to acceptance of this product.
