Used as a chiral reducing agent in organic synthesis, particularly for the stereoselective reduction of ketones and imines to produce enantiomerically pure alcohols and amines. It is highly effective in asymmetric synthesis, enabling the production of compounds with specific spatial arrangements, which is crucial in the development of pharmaceuticals, agrochemicals, and fine chemicals. The reagent is valued for its ability to provide high enantioselectivity and yield, making it a preferred choice in complex synthetic pathways.
