Used as a Grignard reagent in organic synthesis to form carbon-carbon bonds, particularly in the preparation of biphenyl derivatives. It is employed in the production of pharmaceuticals, agrochemicals, and fine chemicals. The reagent is also utilized in the synthesis of complex organic molecules, such as polymers and liquid crystals, due to its ability to react with various electrophiles like carbonyl compounds. Its application extends to research and development in creating new compounds with potential biological or material properties.
