Diethylzinc is a zinc precursor for the deposition of compound semiconductors used in applications such as light emitting diodes, laser diodes, high performance transistors and high efficiency solar cells.  It is also used to create the transparent conductive oxide layer in thin film solar cells and other thin film processes.

Safety and handling 

Diethylzinc 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. Diethylzinc may undergo exothermic decomposition with evolution of flammable gas above 70°C. The decomposition may become self-accelerating and uncontrollable and may result in a violent runaway reaction if heated above 120°C. Products of complete combustion of diethylzinc are zinc oxide, carbon dioxide and water. Diethylzinc causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling Diethylzinc. 


GHS Hazard and Precautionary Statements

Hazard Statements : H250-H260-H314-H318-H400-H410
Catches fire spontaneously if exposed to air.

In contact with water releases flammable gases which may ignite spontaneously.

Causes severe skin burns and eye damage.

Causes serious eye damage. Very toxic to aquatic life. Very toxic to aquatic life with long lasting effects.


Precautionary Statements : P210-P273-P305+P351+P338-P309-P310-P501A
Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Avoid release to the environment.

IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. IF exposed or if you feel unwell: Immediately call a POISON CENTER or doctor/physician. Dispose of contents/container in accordance with local/regional / national / international regulations.
