Crystals of sublimed 2-(trifluoroacetyl)pyrrole.

The raw reaction product what was an off-white crystalline compound with a melting point 50 °C was loaded in a test tube and left there for a few months. For now, these crystals formed at the wall what are perfectly pure 2-(trifluoroacetyl)pyrrole.

If this compound is left on a Petri dish for a day, most of it will sublime away.
