C20H14O3

C20H14O3 is the molecular formula for a compound that can exist in several isomeric forms. One well-known isomer with this formula is Benzophenone-3 (BP-3), also known as oxybenzone. Benzophenone-3 is an organic compound widely used as an ingredient in sunscreens and other personal care products due to its ability to absorb ultraviolet (UV) radiation. It functions as a UV filter, protecting the skin from the harmful effects of both UVA and UVB rays.

The chemical structure of C20H14O3 generally features a core of aromatic rings, indicating it belongs to the class of organic compounds. The specific arrangement of these rings and the three oxygen atoms defines the particular isomer and its properties. Benzophenone-3, for instance, has a benzophenone core with a hydroxyl group and a methoxy group attached. This specific structure allows it to absorb UV light and dissipate the energy as heat.

Beyond its use in sunscreens, compounds with the C20H14O3 formula may find applications in other areas, such as plastics as UV stabilizers to prevent degradation from sunlight, or in research laboratories as chemical intermediates. The synthesis of these compounds typically involves reactions common in organic chemistry, such as Friedel-Crafts acylation or etherification. The environmental fate and potential biological effects of certain isomers, particularly Benzophenone-3, are subjects of ongoing scientific research and public discussion.
