摘要
In the title compound, C 30 H 38 O 4 S, the hydroxyl group bonded to one phenyl ring and an O atom of the benzene-sulfonate group attached to the other phenyl ring of the biphenyl backbone of the structure are involved in an intra-molecular O - H⋯O hydrogen bond. The dihedral angle between the planes of the two aromatic rings of the biphenyl unit is 70.4 (2)°.
