Used as a versatile reagent in organic synthesis, particularly in the formation of carbon-carbon bonds. It acts as a nucleophile in reactions with carbonyl compounds such as aldehydes, ketones, and esters, enabling the synthesis of alcohols and extended hydrocarbon chains. Commonly employed in Grignard reactions, it facilitates the alkylation of various electrophilic substrates. Its solution form allows for precise dosing and improved handling in industrial and laboratory settings, making it suitable for pharmaceutical intermediates and fine chemical production.
