Hydroquinine is widely used in the pharmaceutical industry as a chiral catalyst in asymmetric synthesis, particularly in the production of enantiomerically pure compounds. It plays a crucial role in the synthesis of complex molecules, including active pharmaceutical ingredients (APIs) for drugs targeting cardiovascular diseases, infections, and neurological disorders. Additionally, it is employed in the development of antimalarial medications due to its structural similarity to quinine. In research, hydroquinine is utilized as a reference standard in analytical chemistry for studying stereoselective reactions. Its application extends to organic synthesis, where it aids in the preparation of fine chemicals and intermediates with high enantiomeric purity.
