Benzophenone is a naturally occurring organic compound with the formula (C 6 H 5) 2 CO, generally abbreviated Ph 2 CO. Benzophenone has been found in some fungi, fruits and plants, including grapes. [4] It is a white solid with a low melting point and rose-like odor [5] that is soluble in organic solvents. Benzophenone is the simplest ...
Many ketones contain the benzoyl group. They have the formula C 6 H 5 CO–R, an important example being benzophenone. Benzoyl esters and amides are common in organic chemistry. The esters are used as a protecting groups in organic synthesis, [4] which can be easily removed by hydrolysis in dilute basic solution.

Metabolic pathway of Benzophenone-3. Benzophenones (BPs) are widely used in UV filters, fragrance enhancers, and plastic additives. The major sources of BP-3 are reported to be human recreational activities and wastewater treatment plant (WWTP) effluents. The anionic forms of both BP-3 and 4-OH-BP3 can undergo direct photodegradation. The ...
