Organic synthesis, hydrazilinating agent of alkynes. 1. It is used as an endcaping agent when preparing α- and α, omega-hydrogen silicon-end silicone polymers. 2. Use as quenching agent when preparing high-strength, low-density Si-C/Si-N ceramics. For the preparation of vinyl dimethical, vinyl dimethicals can be used for palladium-catalyzed cross-coupling reaction of aryl Chemicalbook iodine3, and tetramethyldisilazane can be prepared after ammonilysis of this product. 4. Raw materials for the preparation of silicone surfactants. 5. Modified with silicone, polyolefin, polyacrylate, polyamide, polyimide, polyester, polyurethane, epoxy, etc., this product is used as the basic raw material.
