Tetradecylisocyanate is primarily used in the synthesis of various organic compounds, particularly in the production of urethane polymers and coatings. Its reactive isocyanate group allows it to form strong bonds with hydroxyl-containing compounds, making it valuable in creating durable and flexible materials. It is also employed in the development of adhesives and sealants, where its properties enhance adhesion and resistance to environmental factors. Additionally, it finds application in the modification of surfaces to improve water repellency and chemical resistance. In research, it serves as a building block for synthesizing specialized chemicals with tailored properties.
