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 ...
Oxybenzone or benzophenone-3 or BP-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound belonging to the class of aromatic ketones known as benzophenones. It takes the form of pale-yellow crystals that are readily soluble in most organic solvents.
3,3’,4,4’-Benzophenone tetracarboxylic dianhydride (BTDA) is chemically, an aromatic organic acid dianhydride. It may be used to cure epoxy-based powder coatings. It has the CAS Registry Number of 2421-28-5 and a European Community number 219-348-1. It is REACH and TSCA registered. The formula is C 17 H 6 O 7 with a molecular weight of 322. ...
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.

Sulisobenzone (benzophenone-4) is an ingredient in some sunscreens which protects the skin from damage by UVB and UVA ultraviolet light. [ 2 ] [ 3 ] Its sodium salt, sulisobenzone sodium , is also referred to as benzophenone-5 .
Patrick went undefeated in county high-school tournaments. He made stickers with the words “STATE CHAMP” written on them in black marker and put them all over the house.
X-ray structure of DNP-derived hydrazone of benzophenone. Selected parameters: C=N, 128 pm; N-N, 1.38 pm, N-N-C(Ar), 119 [4] When 3-heptanone is added to a solution of 2,4-DNPH and heated, an orange-red precipitate forms. DNP-derived hydrazones have characteristic melting points, facilitating identification of the carbonyl.
