similar to that of 4,6-octadien-3-one (Buttery, 1978), but sufficient differences exist to make the assignment doubtful. The other, at 71.06 min, appears to be a monounsaturated compound, possibly 2-octen-4-one.Pyrrole is the only nitrogen-containing constituent fully identified. A peak at 120.85 min contains two compounds, one of which is definitely biphenyl. When the biphenyl MS is subtracted from the combined MS, a MS identical with that of indole remains. However, indole's retention time is approximately 3 min longer. The m/e intensities for 116, 117, and 118 are 11, 100, and 11%, respectively, ruling out the related benzyl cyanide and isocyanide, as well as the methyl cyano-and isocyanobenzenes, which typically have 116 intensities equal to 40-80% of the 117
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
