Used as a reducing agent in organic synthesis, particularly for selective reductions where steric bulk helps control reactivity. Its unique structure allows for chemoselective transformations in complex molecules, making it valuable in pharmaceutical and fine chemical manufacturing. Often employed in the reduction of carbonyl groups and imines when milder or more selective conditions are needed. The tert-butylthio groups enhance stability and influence solubility, improving handling and reaction performance in non-aqueous solvents.
