Used primarily as an intermediate in organic synthesis, especially in the production of specialty chemicals and fragrances. Its alkyne functionality allows it to participate in coupling reactions, making it valuable in the development of complex organic molecules. It is also utilized in research settings for the synthesis of long-chain hydrocarbons and surface modifiers. Due to its hydrophobic nature, it finds use in modifying surfaces for water-repellent coatings. Additionally, it serves as a building block in the preparation of certain polymers and lubricants where linear, unsaturated chains are required.
