Description

Application
HMDS is widely used as a silylating agent in organic synthesis in semiconductor manufacturing for surface treatment and in laboratories to prepare samples for analysis (e.g. gas chromatography).

Purpose
The main purpose of HMDS is to introduce trimethylsilyl groups to compounds making them more volatile stable and suitable for analytical or industrial processes.

General Description
111333-Hexamethyldisilazane (HMDS) is a volatile organosilicon compound composed of silicon nitrogen and methyl groups known for its hydrophobic and silylating properties.
