Editing Benzophenone (section)

==Uses==
Benzophenone can be used as a [[Photoinitiator|photo initiator]] in [[ultraviolet]] (UV)-curing applications<ref>{{cite journal|title=Patterning dewetting in thin polymer films by spatially directed photocrosslinking|author1=Carroll, G.T. |author2=Turro, N.J. |author3=Koberstein, J.T. |journal=Journal of Colloid and Interface Science|year=2010|volume=351|issue=2|pages=556–560|doi=10.1016/j.jcis.2010.07.070|pmid=20728089 |bibcode=2010JCIS..351..556C }}</ref> such as inks, imaging, and clear coatings in the [[printing]] industry. Benzophenone prevents UV light from damaging scents and colors in products such as perfumes and soaps.

Benzophenone can also be added to plastic packaging as a UV blocker to prevent photo-degradation of the packaging polymers or its contents. Its use allows manufacturers to package the product in clear glass or plastic (such as a [[PETE]] water bottle).<ref>{{cite web|last1=Dornath |first1=Paul John |title=Analysis of Chemical Leaching from Common Consumer Plastic Bottles Under High Stress Conditions |url=https://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/17627/Dornath%20thesis.pdf?sequence=1 |access-date=26 February 2015 |page=32 |date=2010 |url-status=dead |archive-url=https://web.archive.org/web/20150226053029/https://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/17627/Dornath%20thesis.pdf?sequence=1 |archive-date=26 February 2015}}</ref> Without it, opaque or dark packaging would be required.

In biological applications, benzophenones have been used extensively as photophysical probes to identify and map peptide–protein interactions.<ref>{{cite journal|last=Dorman|first=Gyorgy|author2=Prestwich, Glenn D.|title=Benzophenone Photophores in Biochemistry|journal=Biochemistry|date=1 May 1994|volume=33|issue=19|pages=5661–5673|doi=10.1021/bi00185a001|pmid=8180191}}</ref>

Benzophenone is used as an additive in flavorings or perfumes for "sweet-woody-geranium-like notes".<ref>{{Cite book|title=Perfume And Flavor Chemicals: (Aroma Chemicals)|last=Arctander|first=Steffen}}</ref>
