2,2'-Dihydroxybenzophenone from TCI is a benzophenone derivative that carries one hydroxyl group in the ortho position on each of its two phenyl rings. It belongs to the non-heterocyclic building blocks and is structurally close to the hydroxybenzophenone family, which is widely known for absorbing ultraviolet light. In the laboratory it serves as an intermediate in organic synthesis, a precursor to the xanthone skeleton, a ligand for metal complexes, and a model compound in studies on the photostabilization of polymer materials.

Its main advantage comes from where its hydroxyl groups sit: right next to the carbonyl group. This arrangement allows intramolecular hydrogen bonds to form. That bonding is the basis of how hydroxybenzophenone UV absorbers work, since the molecule absorbs light energy and releases it as heat without being damaged. The two phenolic groups also allow many kinds of reactions, including etherification, esterification, and intramolecular cyclization. The phenolic and carbonyl oxygen atoms can also bind metal ions together, so the compound is useful in coordination chemistry as well as synthesis.

In Indonesia, this compound is useful to organic chemistry and natural product laboratories because the xanthone skeleton is common in tropical plants such as mangosteen. Researchers who study these natural compounds can use it as a starting material for building xanthone frameworks and related analogues. Polymer and materials laboratories can use it as a reference compound when they study UV absorption and photostabilization. University teaching laboratories can also use it to show hydrogen bonding and phenol reactivity in practice.
