2-[(1R*,4R*)-1,4-Dihy­droxy­cyclo­hex­yl]acetic acid

The title compound, C(8)H(14)O(4), is an isolation product of the aerial parts of Senecio desfontanei. The acetic acid group is oriented at a dihedral angle of 48.03 (9)° with respect to the basal plane of the cyclo­hexane-1,4-diol chair. An intra­molecular O—H⋯O hydrogen bond generates an S(6) ring with an envelope conformation. In the crystal, mol­ecules are linked by O—H⋯O hydrogen bonds, resulting in R (3) (3)(20) ring motifs and C(2) O—H⋯O—H⋯O—H⋯ chains. Overall, a three-dimensional polymeric network arises. A C—H⋯O contact is also present.
