General description

2-(4-Benzoyl-3-hydroxyphenoxy)ethyl acrylate is a derivative of oxybenzone that is widely used as a UV-blocking agent in the fabrication of contact lenses. It contains both a vinyl group and an aromatic benzoyl group which makes it useful in polymerization and crosslinking reactions. This acrylate monomer is commonly used as a building block in the synthesis of polymers utilized in various coatings, adhesives, and dental fillings. Due to its unique structure, it can exhibit desirable properties such as high reactivity, good adhesion to a variety of substrates, and resistance to UV degradation.

Application

2-(4-Benzoyl-3-hydroxyphenoxy)ethylacrylate can be used as a monomer to synthesize fluorine-silicone acrylic resinto improve the UV resistance of the resin and make it more durable andlong-lasting.
