In the title adduct, C5H5NO·C8H12O4, the heterocycle exists in its zwitterionic form. The cyclohexane ring exhibits a chair conformation with the carboxylic acid groups in equatorial and axial orientations. In the crystal, molecules are linked through charge-assisted O-H⋯O-, N+-H⋯O-and N+-H⋯O hydrogen bonds, and an additional series of C-H⋯O contacts, giving a pleated two-dimensional hydrogen-bonded network parallel to (-204).
