Used as a reduced form of nicotinamide derivatives in organic synthesis, particularly as a biomimetic reducing agent in transfer hydrogenation reactions. It mimics the action of NADH (nicotinamide adenine dinucleotide) in biological systems, making it valuable in studies of enzyme mechanisms and in the development of synthetic models for redox processes. Commonly employed in the reduction of carbonyl compounds, imines, and other unsaturated functional groups under mild conditions. Its role as a hydride donor allows for selective reductions in complex molecule synthesis, including pharmaceuticals and natural products.
