Hexamethyldisilazane is suitable for the derivatization of alcohols, U-aminobutyric acid, pesticidal carbamates and urea, 3,4-Dihydroxyphenylglycol, 4-hydroxycoumarins, hydroxyfatty acids, n-hydroxy-2-fluorenylacetamide, kerb cycle acid, malonaldehyde, monoglycerides, phenylpyruvic acid, shikimic acid, unsaturated fatty acid esters (or methyl esters), and related compounds. It may be used as a derivatizing reagent for the analysis of bioamines and their acidic metabolites, phenol, hydroquinone and catechol in urine samples, mixtures of free fatty acids and metal soaps in paint samples using gas chromatography/mass spectrometry (GC/MS).

Features and Benefits

HMDS is inexpensive and has a relatively low boiling point (124-127 °C).         It can be used without solvent but its silylating power can be increased by various (mostly acidic) catalysts.         The only reaction byproduct, ammonia, can leave the reaction mixture as the reaction gŒs to completion.

General description

Hexamethyldisilazane (HMDS) is a commercially available, silylating agent, which is used as an alternative for the preparation of silyl ethers from hydroxyl compounds.
