Abstract The analysis of water‐soluble organic compounds in meteorites provides valuable insights into the prebiotic synthesis of organic matter and the processes that occurred during the formation of the solar system. We investigated the concentration of aliphatic monoamines present in hot acid water extracts of the unaltered Antarctic carbonaceous chondrites, Dominion Range ( DOM ) 08006 ( CO 3) and Miller Range ( MIL ) 05013 ( CO 3), and the thermally altered meteorites, Allende ( CV 3), LAP 02206 ( CV 3), GRA 06101 ( CV 3), Allan Hills ( ALH ) 85002 ( CK 4), and EET 92002 ( CK 5). We have also reviewed and assessed the petrologic characteristics of the meteorites studied here to evaluate the effects of asteroidal processing on the abundance and molecular distributions of monoamines. The CO 3, CV 3, CK 4, and CK 5 meteorites studied here contain total concentrations of amines ranging from 1.2 to 4.0 nmol g −1 of meteorite; these amounts are 1–3 orders of magnitude below those observed in carbonaceous chondrites from the CI , CM , and CR groups.
