Application

HMDS+TMCS+Pyridine in the ratio of 3:1:9 may be used as the silylating agent, during multi-targeted profiling of the major phytohormones by gas chromatography-mass spectrometry (GC-MS).[1] This reagent was used as a derivatizing agent during sample processing during determination of 5-hydroxymethylfurfural in wood using GC-MS method.[2]

In the present investigation we report selection of the N-methyl-N-(tert.-butydimethylsilyl)trifluoroacetamide (MTBSTFA) reagent as the most comprehensive derivatization protocol among 17 tested reactions covering trifluoroacetylation, pentafluorobenzylation, methylations, and trimethylsilylations. MTBSTFA allowed easy and robust tert.-butyldimethylsilyl derivatization of 1-aminocyclopropane-1-carboxylic acid, indole-3-acetic acid
