Overview

Product Introduction

3-bromopropyl trimethoxysilane is a bromo silane. It is popularly used as a silane coupling agent.
3-bromopropyl trimethoxysilane (BPTS) acted as initiating sites for functionalization magnetite (Fe3O4) nanoparticles. A study reports the role of BPTS in attaching a polyelectrolyte to an inorganic alumina substrate during the fabrication of a polymeric humidity sensor.
