Used as a key intermediate in the synthesis of high-performance polymers and specialty polyesters, 1,2-cyclododecanediol contributes to the production of thermally stable and mechanically strong materials. Its rigid cyclic structure enhances the glass transition temperature and crystallinity of polymers, making it suitable for engineering plastics and coatings requiring durability under high-temperature conditions. It is also employed in the development of optical materials and liquid crystals due to its ability to influence molecular alignment and birefringence. Additionally, it serves as a building block in fine chemical synthesis, including pharmaceuticals and agrochemicals, where stereochemistry and ring strain play a role in reactivity.
