Used as a monomer in the synthesis of biodegradable polyesters for biomedical applications such as tissue engineering and drug delivery systems. Its hydroxyl end groups enable controlled polymerization and cross-linking, contributing to tunable mechanical properties and degradation rates. Also employed in the development of soft, flexible coatings and elastomers in specialty polymers due to its aliphatic chain length and aromatic core balance. Shows promise in eco-friendly plastics where hydrolytic stability and processability are required.
