1,1,3,3-Tetramethyldisiloxane TMDSO CAS 3277-26-7 Purity >99.0% (GC)

1,1,3,3-Tetramethyldisiloxane (CAS: 3277-26-7) is soluble in many organic solvents, such as aromatic hydrocarbon and petroleum hydrocarbons, and so on. This product is a kind of widely used organic silicon intermediates, and usually be used as organic silicon blocking agent.  Due to containing reactive Si-H groups in the molecular structure, it can be used in the synthesis of copolymer. It is an important intermediate and an organosilicon terminating agent with a wide range of application fields. It is used for the synthesis of functional end groups containing polysiloxane, it is a high-performance silicone surfactants. It is the important raw material of liquid silicone rubber, modified silicone oil, plastic, resin modifier and dendrimers. Can be used as an important intermediate for the synthesis of various silicone oils, silicone resins, addition silicone rubbers and other organosilicon compounds. Can be used as a basic material for the preparation of high-performance organic silicone surfactants. Can be used as a blocking agent and a reagent for the synthesis of pharmaceutical intermediates. 1,1,3,3-Tetramethyldisiloxane is an organosilane reducing agent that can be used to reduce the formation of sulfides and reductive etherification reactions. It is used to produce addition molding silicone rubber, silicone gel, methyl hydrogen silicone oil and other special additives. A hydrogen-terminated disiloxane that can undergo an addition reaction with unsaturated olefins, so it is widely used to prepare hydrogen-terminated polysiloxanes, which are used as chain extenders or crosslinkers for silicone rubber or synthesize various end-capped siloxane polymers with reactive functional groups, which can be used for the modification of organic polymers by organosilicon copolymerization. It can also be used as a reducing agent in organic synthesis.
