Used in the synthesis of biocompatible polymers, it serves as a key component in drug delivery systems, enhancing the solubility and stability of therapeutic compounds. It is also applied in the modification of proteins and peptides to improve their pharmacokinetic properties. Additionally, it plays a role in the development of hydrogels for tissue engineering, providing a scaffold for cell growth and regeneration. Its hydrophilic nature makes it suitable for use in cosmetic formulations, where it aids in moisture retention and skin hydration.
