Used as a non-toxic, renewable building block in the synthesis of biodegradable polymers such as polyesters and polycarbonates, replacing petroleum-based monomers. Commonly found in eco-friendly plastics for packaging, medical devices, and coatings due to its rigidity and thermal stability. Also applied in the pharmaceutical industry as an intermediate for vasodilator drugs. Increasingly used in cosmetic formulations for its skin-conditioning properties and low irritation potential.
