2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl methacrylate Chemical Properties, Uses, Production

Uses

It finds use

in intraocular lenses,
as a UV absorber (UVAs)

General Description

It is capable of absorbing ultraviolet radiation (UV) and dissipate the energy in the form of heat, in sub-picosecond time scale. For the benzotriazole class of UV absorbers, the mechanism of excited-state deactivation is due to an excited-state intramolecular proton transfer.
