Used as a reducing agent in organic synthesis, particularly for the reduction of carbonyl compounds, imines, and nitro groups. It serves as a source of hydride in the presence of catalysts or Lewis acids. Commonly employed in hydrosilylation reactions, which are key steps in the production of silicon-based materials and pharmaceuticals. Also utilized as a silylating agent to protect functional groups during multi-step syntheses. Plays a role in the preparation of silicon polymers and resins by acting as a chain transfer agent or terminator in polymerization processes. Its volatility makes it suitable for use in gas-phase reactions and thin-film deposition techniques.
