title: 4-(4-Propoxybenzo-yloxy)benzoic acid.
abstract: The title compound, C(17)H(16)O(5), is an important inter-mediate for the synthesis of side-chain ligands for polymeric liquid crystals. The prop-oxy and benzoic acid groups subtend dihedral angles of 4.36 (6) and 55.35 (6)°, respectively, with the central benzo-yloxy unit. The crystal structure is stabilized by an inter-molecular O-H⋯O hydrogen bond.
