3,3′,5,5′-Tetra-tert-butyl-2′-hy­droxy-[1,1′-biphen­yl]-2-yl 4-methyl­benzene­sulfonate

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—H...O_sulfonate 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—H...O hydrogen bonds link the mol­ecules into columns in direction [100].
