产品描述

General description

Hexamethyldisilazane (HMDS) is a commercially available, silylating agent,[5][6] which is used as an alternative for the preparation of silyl ethers from hydroxyl compounds.[6]

Application

Learn more in the Product Information

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,[2] phenol, hydroquinone and catechol[4] in urine samples, mixtures of free fatty acids and metal soaps in paint samples[3] using gas chromatography/mass spectrometry (GC/MS).

Suitable for the derivatization of alcohols, Υ-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.

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 goes to completion.
