Description and Uses

1,1,3,3,5,5-Hexamethyltrisiloxane is involved in the preparation of 2-bis(3-allyl-4-hydroxyphenyl)hexafluoropropane, which is associated with inorganic siloxane polymer and used as a coating material for the detection of toxic chemical warfare agents. It is also used as a silylating agent and to prepare 1,5-Bis[2-(1,2-epoxycyclohex-4-yl)ethyl]-1,1,3,3,5,5-hexamethyltrisiloxane from 4-vinyl-1-cyclohexene-1,2-epoxide by hydrosilylation.
