Product introduction

YAC-OTCS is an amphiphilic molecule consisting of a long-chain alkyl group (C18H37–) and a polar head group (SiCl3–), which forms Self assembled monolayers (SAMs) on various oxidic substrates.

This chlorosilane is flammable, reacts violently with water, and is sensitive to air. It is corrosive and can severely damage mucous membranes.
