ABSTRACT
In the title compound, C(20)H(22)O(8)S, the dihedral angle between the two benzene rings is 81.6â
(3)°. The benzene-connected portions of the alk-oxy substituents are almost coplanar with their respective rings [C-C-O-C torsion angles of 174.77â
(17) and -178.5â
(4)°]. One of the butanoic acid groups is disordered over two conformations with a site-occupancy ratio 0.719â
(6)0.281â
(6). In the crystal, pairs of O-Hâ¯O hydrogen bonds link the mol-ecules into infinite zigzag chains along [130].
