Description

General description

1-(Trimethylsilyl)imidazole-Pyridine mixture is useful for derivatizing wet sugar samples, hindered hydroxyl groups in steroids and, in conjunction with fluorinated acylation reagents, amino acids. For moderately hindered or slowly reacting compounds, pyridine is an especially useful solvent for TMSI because of its ability to act as an HCl acceptor in silylation reactions involving organochlorosilanes.
