Used primarily as an intermediate in organic synthesis, particularly in the preparation of fatty acid derivatives with functional modifications. Its reactive chloromethyl group allows for easy alkylation or introduction of the dodecanoyl chain in pharmaceuticals, agrochemicals, and specialty polymers. Commonly employed in the development of prodrugs where esterification enhances bioavailability. Also utilized in surfactant modification to adjust hydrophobicity and reactivity in coating formulations and biocidal agents.
