Phosgene in deteriorated chloroform: presumptive cause of production of 3,4-dimethyl-5-phenyl-2-oxazolidones in methamphetamine

ConclusionsThe experimental results indicated that DPOs were produced by the reaction of ephedrines with deteriorated chloroform containing phosgene and that the reaction proceeds regardless of chemical forms, even at room temperature. DPOs are useful markers of contact between ephedrines and deteriorated chloroform.
