LS-H13 Triphenylsilanol; Hydroxytriphenylsilane
CAS NO. 791-31-1
Silfluo LS-H13 is Triphenylsilanol (Hydroxytriphenylsilane), a monofunctional phenylsilanol.
The molecule contains three phenyl groups and one silanol (Si–OH) group on a single silicon atom.
The silanol group undergoes condensation with silanols, alkoxy silanes, and hydroxylated surfaces under acid or base catalysis, or functions as a chain end-capping agent in siloxane synthesis.
Three phenyl groups per silicon atom give an exceptionally high refractive index and raise thermal and oxidative stability relative to lower-phenyl-content analogs.
Used as end-capping agent and structural monomer in high-RI phenyl silicone resin synthesis, as pharmaceutical synthesis intermediate, and as precursor for triphenylsilyl-terminated silicone fluids.
Performance equivalent to Dow Z-6800.
