Bis(cyclopentadienyl)magnesium - Cp2Mg

AkzoNobel offers the highest purity bis(cyclopentadienyl)magnesium under the product name of Cp2Mg SSG (Select Semiconductor Grade). Cp2Mg SSG is used as a high quality magnesium precursor for the deposition of compound semiconductors and commonly applied as dopant in GaN based material systems.

Bis(cyclopentadienyl)magnesium 

CAS Number: 1284-72-6
Appearance: yellow crystalline solid
Density, 20°C: 1.1 g/ml
Melting point: 176°C
Boiling point, 760 torr: >300°C (decomposes)
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 Cp2Mg SSG for more information or contact us for detailed specifications. 

Storage
Cp2Mg SSG is stable when stored under a dry, inert atmosphere and away from heat. Bis(cyclopentadienyl)magnesium 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
Cp2Mg SSG 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. If heated above elevated temperature, Cp2Mg SSG will undergo exothermic decomposition with evolution of flammable gas. Products of complete combustion of bis(cyclopentadienyl)magnesium are magnesium oxide, carbon dioxide and water. Cp2Mg SSG causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling Cp2Mg SSG. 

Please refer to the Material Safety Data Sheet (MSDS) for further information on the safe storage, use and handling of Cp2Mg SSG. This information should be thoroughly reviewed prior to acceptance of this product.
