In the title molecule, C37H48O4S, the benzene rings in the biphenyl fragment are inclined to each other at 61.1 (1)°. The hydroxy group is involved in a weak intramolecular O-HOsulfonate hydrogen bond. One tert-butyl group is disodered over two orientations in a 0.682 (17):0.318 (17) ratio. In the crystal, weak C-HO hydrogen bonds link the molecules into columns in direction .
