Allgemeine Beschreibung

Hexamethyldisilane (HMDS) is a stable and effectivereagent for trimethylsilylation of hydrogen-labile substrates such as alcohols,amines, and carboxylic acids. It is commonly used for the protection of sensitivefunctional groups during chemical synthesis. Owing to its low cost, high vapor pressure, and safety, itis widely used as a precursor in chemical vapor deposition(CVD) reactions.

Anwendung

Hexamethyldisilane (HMDS) can be used:
  • As a silylating agent in the trimethylsilylation of alcohols under nearly neutral reaction conditions.
  • To control the molecular weights of polypeptides during ring-opening polymerization of α-amino acid N-carboxyanhydrides.
  • To fabricate silicon carbonitride thin films by plasma-enhanced CVD.
  • For specimen preparation for scanning electron microscopy and the preparation of trimethylsilyl ethers from hydroxy compounds.

Leistungsmerkmale und Vorteile

  • High chemicalstability and low molecular weight
  • Nontoxic andcost-effective reagent
  • Ammonia is theonly byproduct generated during silylation
  • Silylationreaction using HDMS is nearly neutral and does not need any precaution

Critical point drying (CPD) is a common method of drying biological specimens for scanning electron microscopy (SEM). Drying by evaporation of hexamethyldisilazane (HMDS) has been described as a good alternative. This method, however, is infrequently used. Therefore, we reassessed HMDS
