Usage
1. Organosilicon Synthesis: Serves as a core hydrogen-containing silicon monomer in addition reactions, used for the preparation of vinyl-terminated polysiloxanes and telechelic silicone oils; it is also a key raw material for producing polyether-modified, epoxy-modified, and amino-modified silicone oils.
2. Silicone Rubber and Organosilicon Resins: Used in the synthesis of addition-curing liquid silicone rubbers, LED encapsulation materials, and organosilicon resins for coatings; it can also be employed to adjust cross-linked structures.
3. Pharmaceuticals and Fine Chemicals: Acts as a silicon-based intermediate for the synthesis of organosilicon-based pharmaceuticals and silane coupling agents.
