This chemical is primarily used as a Grignard reagent in organic synthesis. It is highly reactive and serves as a key intermediate in the formation of carbon-carbon bonds. One of its main applications is in the production of complex organic compounds, such as pharmaceuticals and fine chemicals. It is particularly useful in the synthesis of ethyl-substituted aromatic compounds, which are often found in active pharmaceutical ingredients (APIs) and agrochemicals. Additionally, it is employed in research laboratories for the development of novel organic molecules, enabling the creation of new materials or drug candidates. Due to its sensitivity to moisture and air, it is typically handled under inert conditions, such as in a nitrogen or argon atmosphere.
