Used in organic synthesis as a Grignard reagent to form carbon-carbon bonds, particularly in the production of complex organic molecules. It is applied in the pharmaceutical industry for synthesizing intermediates in drug development. Also utilized in research laboratories for creating fine chemicals and specialty compounds. Its reactivity with carbonyl compounds makes it valuable for constructing alcohols, ketones, and other functionalized aromatic structures. Often employed in the preparation of liquid crystals and advanced materials for electronics.
