2,2′-Dihydroxy-4-methoxybenzophenone is a yellow powder. It is not very soluble in water. 2,2′-Dihydroxy-4-methoxybenzophenone is an ingredient in some sunscreens. As a chemical filter, 2,2′-Dihydroxy-4-methoxybenzophenone absorb these rays to prevent their penetration into the skin and attenuate long-term skin damage caused by UV radiation from the sun.
