The metabolic fate of hexahydro‐1,3,5‐trinitro‐1,3,5‐triazine (RDX) in a mixed culture incubated under methanogenic conditions was studied. Analysis by high‐performance liquid chromatography (HPLC) confirmed the loss of RDX and the formation of mono‐, di‐, and trinitroso‐RDX as transient biodegradation intermediates. An additional peak observed in the HPLC chromatograms was identified by liquid chromatography–mass spectrometry as hydroxylamino‐dinitroso‐1,3,5‐triazine. This is the firstreport identifying hydroxylamino‐dinitroso‐1,3,5‐triazine as a transient intermediate produced during the anaerobic biodegradation of RDX.
