چکیده
The title compound, C(20)H(32)O(2), has been isolated from hydrogenated rosin. There are two independent mol-ecules in the asymmetric unit. In each mol-ecule, the cyclo-hexane ring assumes a chair conformation, while the two cyclo-hexene rings adopt half-chair and envelope conformations. Inter-molecular O-H⋯O hydrogen bonding between carboxyl groups links pairs of independent mol-ecules into dimers.

In the title compound, C(20)H(32)N(+)·C(7)H(7)O(3)S(-), the configurations of the two chiral centers observed in the protonated cation are consistent with previous reports. In the crystal structure, weak inter-molecular N-H⋯O hydrogen bonds link ions into chains which develop along the a axis. The isopropyl group and four CH groups of the attached benzene ring are disordered approximately equal...
