4,4′-Dihydroxybenzophenone is prepared by the rearrangement of p-hydroxyphenylbenzoate: HOC 6 H 4 CO 2 C 6 H 5 → (HOC 6 H 4) 2 CO. Alternatively, p-hydroxybenzoic acid can be converted to p-acetoxybenzoyl chloride. This acid chloride reacts with phenol to give, after deacetylation, 4,4′-dihydroxybenzophenone.

The scientists analyzed blood, urine, feces, and tissue samples and found three metabolites: 2,4-dihydroxybenzophenone (DHB), 2,2-dihydroxy-4-methoxybenzophenone (DHMB) and 2,3,4-trihydroxybenzophenone (THB). [28] [29] To form DHB the methoxy functional group undergoes O-dealkylation; to form THB the same ring is hydroxylated. [27]
There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. [1]
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.
