Used as a Grignard reagent in organic synthesis to form carbon-carbon bonds, enabling the production of alcohols, carboxylic acids, and other complex organic compounds. Applied in polymerization processes as a catalyst or co-catalyst, particularly in the production of polyolefins like polyethylene and polypropylene. Utilized in the preparation of organomagnesium compounds, which serve as intermediates in pharmaceuticals and fine chemicals. Also employed in the synthesis of specialty chemicals, including agrochemicals and dyes, due to its ability to facilitate precise and controlled reactions.
