2-Aminoacetophenone has a grape-like odor. Aminoacetophenone is a pheromone produced by virgin honeybee
queens and released in feces. The pheromone repels and is used to terminate agonistic interactions between queens and workers. A
grape-like odor of 2-aminoacetophenone is of diagnostic importance in detecting the growth of Pseudomonas aeruginosa in culture
and in burn wounds.
| [Chemical Properties]
yellow to yellow-brown liquid | [Occurrence]
Reported present in chestnut honey (>154 ppb)*; green tea? and wine (0.7 to 12.8 μg/L). | [Uses]
2′-Aminoacetophenone may be used as an analytical standard for the determination of the analyte in livestock particulate matter, and grape-derived beverages by gas chromatography-mass spectrometry-olfactometry (GC-MS-O) and GC-MS, respectively. | [Definition]
ChEBI: An aromatic ketone that is acetophenone in which one of the ortho hydrogens of the phenyl group has been replaced by an amino group. | [Preparation]
Synthesis of 2-Aminoacetophenone by reaction of methyl lithium with Isatoic Anhydride in an anhydrous or nearly anhydrous solvent at a reaction temperature of -50°C or less. | [Synthesis Reference(s)]

2′-Aminoacetophenone[551-93-9] is one of the key volatile flavor components of masa corn flour products. It is also reported to be responsible for the grape-like odor in culture media growing Pseudomonas aeruginosa. This grape-like odor is often of diagnostic importance in detecting the growth of Pseudomonas aeruginosa in culture and in burn wounds. |
