Used in the production of water-soluble polymers and copolymers, particularly in the formulation of hydrogels for biomedical applications such as contact lenses and wound dressings. Acts as a reactive intermediate in the synthesis of functional polymers due to the presence of both hydroxyl and amide groups, enabling crosslinking and modification. Employed in coatings, adhesives, and textile finishes where improved flexibility and adhesion are required. Also utilized in the development of stimuli-responsive materials for drug delivery systems.
