SiSiB® PC9230

N,N'-Bis(Trimethylsilyl)urea(BSU).
Synonym: 1,3-Bis(trimethylsilyl)urea.

Chemical Structure

Introduction

SiSiB® silazane is any hydride of silicon and nitrogen having a straight or branched chain of silicon and nitrogen atoms joined by covalent bonds. By extension, the word is also used for any organic derivative of such compounds. They are analogous to siloxanes, with -NH- replacing -O-. Their individual name is dependent on the number of silicon atoms in the chemical structure.
