Used as an ester-based coupling agent in organic synthesis, particularly in peptide synthesis where it activates carboxylic acids for amide bond formation. It enhances reaction efficiency by improving solubility and reducing racemization. Also employed in the preparation of biodegradable surfactants and lipid derivatives due to its long aliphatic chain, making it suitable for applications in pharmaceuticals, cosmetics, and agrochemicals. Its structure allows for compatibility with both polar and nonpolar systems, enabling use in multi-phase reactions.
