Two homologous series of alkylpyridines (CnH2n-5N and CnH2n-7N) were identified in the methanol extract of the Murchison meteorite by liquid chromatography/high-resolution mass spectrometry. The wide range of saturated- and unsaturated-alkylated (C1 to C21) pyridines is more diverse than previously found, and could be produced by reactions of aldehyde condensation and aldehydes with NH3 by imine formation in Solar or pre-solar environments. This finding implies a high aldehyde activity under alkaline conditions in the presence of ammonia during the chemical evolution of soluble organic matters detected in a CM2-type carbonaceous meteorite.
