2. 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).Without it, opaque or dark packaging would be required.3. In biological applications, benzophenones have been used extensively as photophysical probes to identify and map peptide–protein interactions.
4. Benzophenones can be used as pharmaceutical intermediates, cosmetic perfumes and pesticides.
