title: 3,3',5,5'-Tetra-tert-butyl-2'-hy-droxy-[1,1'-biphen-yl]-2-yl 4-methyl-benzene-sulfonate.
abstract: In the title mol-ecule, C(37)H(48)O(4)S, the benzene rings in the biphenyl fragment are inclined to each other at 61.1 (1)°. The hy-droxy group is involved in a weak intra-molecular 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 mol-ecules into columns in direction [100].
