2-Acetyl-1-methylpyrrole Usage And Synthesis
DescriptionMay be prepared from Af-methyl pyrrole and Grignard reagent; by acetylation of 1-methyl-pyrrole.
Chemical PropertiesCLEAR COLOURLESS TO LIGHT BROWN LIQUID
OccurrenceReported found as a component in coffee aroma, asparagus, crispbread, cooked beef, black tea, okra and clam.
Uses2-Acetyl-1-methylpyrrole was employed as model pyrrole to investigate the antioxidative activity of nonenzymatic browning reactions. It was employed as catalyst for the sulfonylation of spectinomycin.
DefinitionChEBI: A pyrrole carrying methyl and acetyl substituent at the 1- and 2-positions respectively.
PreparationFrom N-methyl pyrrole and Grignard reagent; by acetylation of 1-methyl-pyrrole.
Aroma threshold valuesDetection: 100 ppb
