Used in chiral resolution and asymmetric synthesis due to its enantiomeric purity, serving as a chiral auxiliary or resolving agent for racemic mixtures. Commonly employed in pharmaceutical intermediates to control stereochemistry during drug synthesis. Also applied in the preparation of liquid crystals and specialty esters for fragrances, where its stereochemistry influences sensory properties. Its carboxylic acid functionality allows for easy derivatization into amides or esters for targeted molecular design.
