General description
tert-Butyldimethylsilylimidazole solution is a derivatizing reagent. It is most effective for silylating multiwall carbon nanotubes (MWNT).
Application
It was used to convert oxysterols to tert-butyldimethylsilyl (TBDMSi) ethers for 18O enrichment during oxysterols determination in plasma and liver, using gas/liquid chromatography-mass spectrometry analysis.

Cholesterol oxidation products (oxysterols) have been detected in many different tissues, often at concentrations 10(3) to 10(4) times lower than cholesterol. This constitutes a considerable risk of quantitation errors, since even a minor oxidation of cholesterol during sample processing would

Five dehydrated compounds obtained from a tert-butyldimethylsilylchloride/imidazole or an aqueous hydrochloric acid treatment of 17 alpha-butyl-3-O-methyl estradiol in refluxing solvent were purified and characterized. Three compounds were obtained from a direct vicinal proton elimination, the two others from a vicinal

The use of gas-liquid chromatography and mass spectrometry with derivatizing agents that give stable derivatives and consistent fragmentation patterns allows for accurate identification of a variety of compounds. In this study either N-methyl-N-tert.-butyldimethylsilyltrifluoroacetamide or N-tert.-butyldimethylsilylimidazole were employed to derivatize a
