N-trifluoroacetimidazole. E na le litšobotsi tse latelang:

1. Ponahalo: N-trifluoroacetamidazole ke kristale e tiileng e se nang 'mala.
2. Solubility: E ka qhibiliha ka har'a li-solvents tse ngata, tse kang ethanol, ethyl acetate le dimethylformamide, joalo-joalo.
3. Ho tsitsa: N-trifluoroacetamidazole e na le botsitso bo botle ho mocheso le khanya.

N-trifluoroacetimidazole e sebelisoa haholo-holo tšimong ea organic synthesis 'me hangata e sebelisoa e le hydrofluorate formation reagent bakeng sa metsoako ea lintho tse phelang. E ka sebelisoa ho hlahisa metsoako e fapaneng e nang le lihlopha tsa trifluoroacetyl, tse kang ketone le alcohols, enol ethers le esters.
