Used as a chiral auxiliary and resolving agent in organic synthesis, particularly in the separation of enantiomers of racemic acids. Its rigid cyclohexane backbone and two amide groups allow it to form diastereomeric complexes with chiral carboxylic acids, enabling effective crystallization-based resolution. Commonly applied in the pharmaceutical industry for the purification of enantiomerically pure intermediates. Also employed in asymmetric synthesis where stereochemical control is critical.
