Used as a chiral reducing agent in organic synthesis, particularly for the enantioselective reduction of prochiral ketones to produce optically active secondary alcohols. It is highly effective in asymmetric synthesis, enabling the production of compounds with high enantiomeric purity, which is crucial in the pharmaceutical industry for the development of chiral drugs. Its application extends to the synthesis of complex natural products and fine chemicals, where precise control over stereochemistry is essential.
