2,4,4'-trihydroxybenzophenone

Synonyms: "(2,4-dihydroxyphenyl)(4-hydroxyphenyl)methanone"

Source: 2,4,4'-trihydroxybenzophenone belong to hydroxybenzophenones, which are used as UV stabilizers in plastic surface coatings on food packaging to prevent polymer degradation and loss of quality of the packed food owing to UV light irradiation. These compounds may be transferred from the packaging to the contents, and subsequently ingested by humans. However, they are natural components of plants such as mango and muscat grape, and are also used as flavorings.
