2-Hydroxy-4-(octyloxy)benzophenone (HOBP) is a UV based absorber that has 2-hydroxybenzophenone as a functional group. It can be used to enhance the light fastness of polymers using UV absorbers with sulfur and phosphorus compounds.HOBPs are UV absorbers for insulating plastics, which can be incorporated with active layers to increase the stabilization of organic solar cells (OSCs). It may be incorporated in parylene C films to enhance the light stability, which can be potentially used as a moisture transfer membrane for electronic boards and photovoltaics.
2-Hydroxy-4-(octyloxy)benzophenone serves as a stable, bench-ready UV absorber with proven utility in polymer stabilization and cosmetic formulations. Its ortho-hydroxy benzophenone core enables efficient hydrogen bonding and intramolecular proton transfer, enhancing photochemical durability. The octyloxy substituent improves solubility in nonpolar matrices while maintaining excellent thermal stability. Functions effectively in both polyolefin and resin systems, offering broad-spectrum protection against UV degradation without significant yellowing.
