Used in the synthesis of functional polymers and hydrogels due to its catechol group and polymerizable acrylamide moiety. The catechol structure enables strong adhesion to various surfaces, including metals and oxides, making it suitable for bioadhesives and coating materials. It is also employed in biomedical applications such as tissue engineering and drug delivery systems, where its biocompatibility and ability to form cross-linked networks are advantageous. Additionally, it serves as a monomer in developing stimuli-responsive materials that react to pH, temperature, or metal ions.
