Isosorbide is a bicyclic synthetic compound from the gathering of diols and the oxygen-containing heterocycles, containing two melded furan rings. Isosorbide is currently of great scientific and technical interest as a monomer building block for biopolymeric polycarbonates such as polyesters, polyurethanes and epoxides
