2-Acetyl pyrrole Usage And Synthesis
Description
2-acetyl pyrrole is a colorless or yellow liquid. It occurs naturally in cereals and cereal product and has an odor reminiscent of walnut, licorice, baked bread, baked hazelnut, and fish. It is used as a food additive, such as in cocoa, rum, brandy, caramel.
Description
Methyl 2-pyrrolyl ketone is like bread, walnut, licorice. May be prepared from pyrryl magnesium iodide and acetyl chloride; a volatile flavor component in roasted filberts.
