In the title compound, C(20)H(22)O(8)S, the dihedral angle between the two benzene rings is 81.6 (3)°. The benzene-connected portions of the alk-oxy substituents are almost coplanar with their respective rings [C-C-O-C torsion angles of 174.77 (17) and -178.5 (4)°]. One of the butanoic acid groups is disordered over two conformations with a site-occupancy ratio 0.719 (6):0.281 (6). In the crystal, pairs of O-H⋯O hydrogen bonds link the mol-ecules into infinite zigzag chains along [130].
在标题化合物C₂₀H₂₂O₈S中，两个苯环之间的二面角为81.6 (3)°。烷氧基取代基与苯相连的部分与其各自的环几乎共面[C-C-O-C扭转角分别为174.77 (17)°和 -178.5 (4)°]。其中一个丁酸基团在两种构象上无序，占位比为0.719 (6):0.281 (6)。在晶体中，O-H⋯O氢键对将分子沿[130]连接成无限之字形链。
