Used primarily as a reducing agent in organic synthesis, it facilitates the reduction of various compounds, including nitro groups to amines and sulfoxides to sulfides. It is also employed in the preparation of pharmaceuticals, where it aids in the synthesis of active pharmaceutical ingredients (APIs). Additionally, it serves as a key intermediate in the production of dyes and pigments, contributing to the development of colorants with specific properties. In polymer chemistry, it is utilized to modify polymer chains, enhancing their stability and performance. Its role in chemical research includes acting as a reagent for studying reaction mechanisms and developing new synthetic pathways.
