General description

Hexamethyldisilazane (HDMS) is an organoslicon compound.HDMS is a colorless liquid used as a reagent and precursor in organic synthesis and organometallic chemistry.

Application

Used in
  • condensation reactions of heterocyclic compounds, such as derivatives of xanthine
  • adhesion promoter for photoresist in photolithography
  • electron microscopy, as an alternative to critical point drying during sample preparation
  • pyrolysis-gas chromatography-mass spectrometry, in order to enhance detectability of compounds with polar functional groups.

Packaging

Alpha-amino acids were pyrolysed at 600 degrees C in the presence of hexamethyldisilazane (HMDS) and the formed volatile products were analysed on line by gas chromatography-mass spectrometry (GC-MS). Glycine, alanine, valine, leucine, isoleucine, norleucine, methionine, phenylalanine yielded principally the trimethylsilyl...

Poly-substituted xanthine derivatives are an important class of compounds in medicinal chemistry. Substitution at the 8-position of the purine ring is generally accessible by ring closure of a carboxamido-substituted uracil precursor.

Three different drying methods, critical-point drying (CPD), Peldri II, and hexamethyldisilazane (HMDS), were compared using representative animal (rat kidney, trachea, duodenum, lung, and red blood cells) and plant (leaves from ten species of monocotyledons and dicotyledons) specimens. All three drying...
