LS-M121 Methyldiphenylmethoxysilane
CAS NO.: 18407-48-2
Silfluo LS-M121 is Methyldiphenylmethoxysilane, a monofunctional diphenyl-functional methoxysilane.
The molecule contains two phenyl groups, one methyl group, and one hydrolyzable methoxy group on silicon.
The monofunctional methoxy group limits condensation to single-point reactions, making it suited for chain end-capping and molecular weight control in siloxane polymer synthesis.
The diphenyl substitution raises refractive index and thermal stability of derived siloxane structures; the methyl group contributes chain flexibility relative to triphenylsilyl analogs.
Used as precision end-capping agent in phenyl silicone resin and fluid synthesis, and as reactive modifier in phenyl silicone rubber formulations.
