Used in the synthesis of specialty chemicals and pharmaceuticals, particularly as a building block for omega-functionalized fatty acid derivatives. It serves in the preparation of intermediates for hormone analogs and bioactive molecules due to its terminal alkyne group, which allows for use in click chemistry reactions. Also employed in polymer chemistry to introduce reactive sites into macromolecules, enabling crosslinking or functionalization of materials. Its structure supports applications in agrochemicals and fragrances where long-chain alkynoic acids are required.
