Description

General description

BSA+TMCS combination, is one of the most commonly used silylating reagents. BSA is readily used for silylating a wide range of functional groups such as non-sterically hindered alcohols, amides, amines, amino acids, carboxylic acids, and enols. TMCS is a silylation catalyst always used with other silylation reagents to increase the reactivity in derivatization of alcohols, alkaloids, amines, biogenic amines, carboxylic acids, phenols, and steroids.

Application

Learn more in the Product Information

Suitable for the derivatization of α-ketoacids, amines, amino acids, cycloserine, histamine and metabolites, phenylethylamines, phosphatidylserines and tryptamines. BSA+TMCS may be used as a derivatizing reagent for the determination of steryl glycosides in biodiesel using gas chromatography–mass spectrometry.

Suitable for the derivatization of a-ketoacids, amines, amino acids, cycloserine, histamine and metabolites, phenylethylamines, phosphatidylserines and tryptamines.

Features and Benefits

• BSA+TMCS has good solvent properties and can function as a silylation reagent without additional solvents.        
• Alternatively, the mixture is very soluble in most commonly used silylation solvents.        
• This combination is extremely sensitive to moisture and should be handled under dry conditions.

Other Notes
