HENGDA-M7123 - n-Dodecyltrimethoxysilane

HENGDA-M7123

n-Dodecyltrimethoxysilane is an organosilane compound with the chemical formula C₁₅H₃₃O₃Si. It consists of a dodecyl group (C₁₂H₂₅) attached to a silicon atom with three methoxy groups (-OCH₃).
Key aspects of n-dodecyltrimethoxysilane:
Dodecyl Group C₁₂H₂₅): An alkyl chain that can influence the properties of the compound.
Trimethoxysilane Group (-Si(OCH₃)₃): Contains three methoxy groups that can undergo hydrolysis to form silanol groups for adhesion and bonding.
