Hexamethyldisilazane Description

CFS-973, Hexamethyldisilazane is a trimethyl terminated silyl amine. It is an extremely strong silyl agent. It can be described as Bis(trimethylsilyl)amine and it’s normally abbreviated as HMDS. Co-Formula can offer commercial CFS-973 under high purity grade. CFS-973 is primarily used as a blocking agent, a surface modifier and a pharmaceutical intermediate for the manufacturer of various chemicals.

Hexamethyldisilazane Application

CFS-973 can be used as a blocking agent to protect sensitive functional groups. It is a reagent for the preparation of trimethylsilyl derivatives;
CFS-973 can be used as a versatile silylation agent and an intermediate for functional silicones and pharmaceutical synthesis;
CFS-973 can be used as a tackifier and adhesion promoter for photoresist;
CFS-973 can be used in GC-MS to enhance the detectability of compounds with polar functional groups;
CFS-973 can be used as surface modifier for inorganic fillers treatment. HMDS coatings on various micro and nanoparticles make them be resistant to water and flocculation.

Hexamethyldisilazane Packaging

CFS-973 is offered in 25L PE pails, 200L PVF steel drums and 1000L IBC totes.
Please contact Co-Formula team for any special packaging request.

Hexamethyldisilazane Storage
