The asymmetric unit of the title compound, C(40)H(60)O(5)S, comprises two diastereomers related, except for the chiral camphor groups, by a pseudo-inversion centre. In both diasteromers, the camphor sulfate moiety maintained the absolute configuartion (R,S) of the precursor. However, the absolute configurations at the methine C atoms are of opposite chirality. Both mol-ecules reveal intra-molecular O-H⋯O hydrogen bonds, whereas van der Waals inter-actions define the crystal packing.
