Propyltrimethoxysilane is an organosilane compound with the chemical formula C₃H₉SiO₃. It consists of a propyl group (C₃H₇) attached to a silicon atom with three methoxy groups (-OCH₃).
Key aspects of propyltrimethoxysilane:
Propyl Group (C₃H₇): Provides an alkyl chain that can influence the properties of the compound.
Trimethoxysilane Group (-Si(OCH₃)3₃): Contains three methoxy groups that can undergo hydrolysis to form silanol groups for adhesion and bonding.
