TMSI:Pyridine (1:4) reagent-solvent formulation used for one-step derivatizations
Derivatizes hydroxyl and polyhydroxyl compounds
Will not derivatize amino groups
Ideal for wet or dry carbohydrates
Used to detect adulterated juices
Tri-Sil Z is a mixture of trimethylsilylimidazole (TMSI) in dry pyridine (1.5 mEq/ml = 1 part TMSI: 4 parts pyridine) and is used primarily for derivatizing hydroxyl compounds, particularly carbohydrates, and does not react with amines. Tri-Sil Z can be used in the presence of water as long as there is enough reagent to react with both the water and the sample. The reagent reacts with water in a 2:1 ratio.
Tri-Sil Z has been used successfully for the silylation of alcohols and phenols, nucleotides, indoles, glycols and polyglycols, amino acids, steroids, vitamins, organic acids, barbituarates, hydroxyl acids, flavonoids, carbohydrates, narcotics, hydroxylamines
