LS-M531 3,3,3-Trifluoropropyl) Methyldimethoxysilane
CAS NO. 358-67-8

Name: LS-M531 3,3,3-Trifluoropropyl) Methyldimethoxysilane
Brand: Nanjing Silfluo New Material Co., Ltd.
Availability: InStock

Silfluo LS-M531 is 3,3,3-Trifluoropropylmethyldimethoxysilane, a fluoroalkyl-functional dimethoxysilane.

The molecule contains one trifluoropropyl group, one methyl group, and two hydrolyzable methoxy groups on silicon.

The difunctional methoxy structure limits hydrolyzable group count compared with trifunctional fluoroalkyl silanes, giving different condensation behavior and chain-termination character.

Used as monomer or intermediate for preparing fluorosilicone fluids, fluorosilicone elastomer bases, and fluoroalkyl-modified siloxane materials.

Equivalent reference: Shin-Etsu KBM-7102.
