Tetramethyl-3,3-diphenyltrisiloxane is an organosilicon compound with a chain structure composed of three silicon atoms, with one methyl group and one phenyl group at each end. This structure endows it with high thermal stability and low-temperature flexibility. It is commonly used as an intermediate for organic silicon materials, such as in the synthesis of silicone oil, silicone rubber, and silicone resin.
