The molecule is built on a chroman scaffold, a bicyclic framework composed of a benzene ring fused to a six-membered heterocycle containing one oxygen atom. The oxygen is positioned adjacent to the fused junction.

There are two substituents on the chroman framework:
1. On the benzene portion: a ring carbon meta to the fused junction carries a hydroxy group.
2. On the heterocyclic portion: the carbon meta to the ring oxygen bears a phenyl substituent. This phenyl ring carries two hydroxy groups: one ortho and one para relative to the point of attachment.
