Acetylpyrazine C화학적 특성, 용도, 생산
화학적 성질
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.출처
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.용도
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
제조 방법
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.정의
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.일반 설명
2-Acetylpyrazine has been identified as one of the volatile flavor constituents in popcorn, wheat and rye bread crust.참고 문헌
