title: 3-(2-Formyl-phen-oxy)propanoic acid.
abstract: In the structure of the title compound, C(10)H(10)O(4), the carboxyl group forms a catemer motif in the [100] direction instead of the expected dimeric structures. The carboxylic acid group is found in the syn conformation and the three-dimensional organization in the crystal is based on C-H⋯O and O-H⋯O interactions.
