Hydrosilane is an organosilicon compound containing a silicon-hydrogen bond (Si-H), which is widely used in organosilicon chemistry and other fields. The main feature of hydrosilane is that the silicon-hydrogen bond is very active and can react with many compounds, especially under catalytic conditions. As a compound with an active silicon-hydrogen bond, hydrosilane is widely used in organic synthesis, surface modification, material synthesis and other fields. Its main functions include: as a reducing agent for reduction reaction, as a silanizing agent for surface modification, participating in cross-linking reactions to enhance material properties, catalyzing certain chemical reactions, etc.
