Used as a versatile nucleophile in organic synthesis, particularly in the preparation of higher hydrocarbons through reactions with carbonyl compounds, epoxides, and other electrophilic substrates. It serves as a key reagent in the formation of carbon-carbon bonds, enabling the elongation of hydrocarbon chains in pharmaceuticals, agrochemicals, and specialty organic molecules. Its long alkyl chain enhances solubility in nonpolar solvents, making it suitable for reactions requiring mild basic conditions and good selectivity. Commonly employed in Grignard reactions where a dodecyl group needs to be introduced into a target molecule.
