Primarily used in organic synthesis, it serves as an alkylating agent to introduce the nonadecyl group into various compounds. It is also employed in the production of surfactants and lubricants due to its long hydrocarbon chain. In research, it is utilized as a precursor for the synthesis of more complex organic molecules, particularly in the development of liquid crystals and polymers. Additionally, it finds application in the preparation of phase-transfer catalysts and as an intermediate in the manufacture of specialty chemicals.
