Used as a selective reducing agent in organic synthesis, particularly for the reduction of aldehydes and ketones in the presence of more sensitive functional groups. It exhibits milder reactivity compared to other borohydride reagents, allowing for greater chemoselectivity. Commonly employed in pharmaceutical and fine chemical manufacturing where controlled reduction is critical. Also utilized in catalytic processes involving transition metals, serving as a source of hydride in cross-coupling reactions. Its stability in certain protic and aprotic solvents enhances its utility in complex reaction systems.
