Used as a chiral reducing agent in organic synthesis, particularly for the stereoselective reduction of ketones to secondary alcohols. It is highly effective in producing enantiomerically pure compounds, making it valuable in the pharmaceutical industry for synthesizing chiral drugs. Additionally, it is employed in the preparation of fine chemicals and intermediates where high enantioselectivity is required. Its ability to provide precise control over stereochemistry makes it a crucial tool in asymmetric synthesis.
