bensofenoon
Bensofenoon is a term that appears to be a misspelling or a non-standard word, making it difficult to identify a specific subject with certainty. If it refers to benzophenone, a common organic compound, then benzophenone is a ketone with the formula (C6H5)2CO. It is used in a variety of applications, including as a UV blocker in plastics and coatings, a photoinitiator in UV-curing applications, and as a component in some sunscreens. Benzophenone is a white crystalline solid that is soluble in organic solvents. Its chemical structure consists of two phenyl rings attached to a carbonyl group.
