A potent mutagen in broiled fish. Part 1. 2-Amino-3-methyl-3H-imidazo[4,5-f]quinoline

Abstract
A potent mutagen isolated from a methanol extract of sardines broiled under normal domestic conditions was strongly mutagenic to Salmonella typhimurium TA98. Its identity has been established as 2-amino-3-methyl-3H-imidazo[4,5-f]quinoline on the basis of spectral evidence and by chemical synthesis.
