Acetylpyrazine Chemical Properties,Uses,Production
Chemical Properties
Acetylpyrazine is a light yellow to yellow-brownish powder that has a nutty, popcorn, bread crust odor. It is one of the volatile aroma components in popcorn, wheat and rye crusts.
Occurrence
Reported found in guava fruit (Psidium guajava L.), wheaten bread, other types of breads, boiled and cooked beef, grilled/roasted uncured pork, pork liver, cocoa, coffee, black tea, roasted barley, roasted filbert (Corylus avellano), roasted peanut (Arachis hypogea), roasted almond (Prunus amygdalus), scallop, filberts, popcorn and sesame oil.
Uses
Acetylpyrazine has been used in synthesis of:
7-heteroaryl-pyrazolo[1,5-a]pyrimidine-3-carboxamides
copper (II) complexes with di-imine ligands
N(4) substituted thiosemicarbazones
Definition
ChEBI: 2-acetylpyrazine is a pyrazine that is substituted by an acetyl group at position 2. It has been identified as one of the volatile flavor constituents in popcorn, bread crust, vinegar, and potato snacks. It has a role as a flavouring agent. It is an aromatic ketone and a member of pyrazines.
Preparation
synthesis of acetylpyrazine: By the ester condensation of EtO2 C-pyrazine; by dehydrating pyrazynamide with POCI3 and then reacting the resulting 2-cyano-pyrazine with methyl magnesium bromide.
General Description
2-Acetylpyrazine has been identified as one of the volatile flavor constituents in popcorn, wheat and rye bread crust.
