Descrizione generale

2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl methacrylate is an organic compound that belongs to the class of acrylate monomers. It is commonly used as a UV absorber or stabilizer in polymers, coatings, adhesives, intraocular lenses, and other materials to protect them from the harmful effects of UV radiation.

Applicazioni

2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl methacrylate can be used:
  • To prepare a polymer material by copolymerization with 2-hydroxy-4-acryloyloxybenzophenone (HABP). The synthesized polymer can be applied to cotton fabric for UV protection.
  • In the preparation of ultraviolet (UV) protective textiles. It is grafted onto the fabric via polymerization to create a UV-protective coating.
  • As a monomer in synthesizing fluoroalkyl end-capped oligomers with good surface-active properties.
  • It is also used as a UV absorber (UVAs) in intraocular lenses.

The use of enzymes in conjunction with inorganic photocatalysts requires stability against photooxidation. In this paper, we describe enhanced stabilization of a model enzyme, chymotrypsin, to photooxidation driven by titanium dioxide exposed to ultraviolet light (TiO(2)-UV). Stabilization is achieved conjugating

Continuous Flow Manufacturing for Monomer Synthesis

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.
