Highlights

  • HMDS:TMCS:Pyridine (2:1:10) reagent-catalyst-solvent formulation for one-step derivatizations
  • Derivatizes carbohydrates, phenols, steroids, sterols, organic acids, alcohols and some amines

Applications

The Pierce Tri-Sil Reagent is composed of HMDS, TMCS and high purity pyridine. It is useful for rapid production of TMS derivatives of polar compounds for gas chromatographic determination and biochemical synthesis. Tri-Sil Reagent is ideal for GC determination of the following:

  • Sugars1,6
  • Alcohols1
  • Phenols7
  • Steroids8,9
  • Sterols10,11
  • Bile acids and other organic acids12-14
  • Some amines15-17

Tri-Sil Reagent is based on the procedure of Sweeley, et al.1 and is used for the optimal conversion of organic hydroxyland polyhydroxyl compounds into TMS ethers. The versatility, speed and ease of use of our Tri-Sil Reagent has made it the most widely used silylation formulation available.

Note: Not recommended for 3-ketosteroids
