Hexacosanedioic acid is primarily used in the production of high-performance polymers and specialty materials. Its long-chain structure makes it suitable for creating durable and heat-resistant plastics, which are often employed in automotive and aerospace industries for components that require exceptional strength and stability under extreme conditions. Additionally, it serves as a precursor in the synthesis of advanced lubricants and coatings, providing enhanced wear resistance and longevity. In the field of biomedicine, it is explored for its potential in developing biocompatible materials for medical devices and drug delivery systems. Its unique properties also make it valuable in research applications, particularly in studying lipid metabolism and the behavior of long-chain fatty acids.
