Isomannide is widely used as a building block in the production of biodegradable polymers, particularly in the synthesis of polyesters and polycarbonates. Its rigid structure and diol functionality make it a valuable monomer for creating materials with enhanced thermal and mechanical properties. These polymers are often utilized in the manufacturing of eco-friendly plastics, coatings, and adhesives, contributing to sustainable material development. Additionally, isomannide is employed in the pharmaceutical industry as a chiral intermediate for the synthesis of various drugs, leveraging its stereochemistry to produce optically active compounds. Its applications also extend to the field of specialty chemicals, where it is used to develop high-performance resins and additives.
