Used as a Grignard reagent in organic synthesis to form carbon-carbon bonds, enabling the creation of complex molecules. Commonly applied in the production of pharmaceuticals, agrochemicals, and fine chemicals. It reacts with carbonyl compounds like aldehydes, ketones, and esters to produce secondary and tertiary alcohols. Also utilized in the synthesis of aromatic compounds and intermediates for further chemical transformations. Its reactivity makes it valuable in research and industrial processes for constructing tailored organic structures.
