Some problems in the detection of strong mutagen MX formed by chlorinating the aromatic acids and phenolic compounds

Ten compounds with aromatic acid and phenolic structure were chlorinated at laboratory conditions and MX analysis by GC/MS at scan mode. None of these compounds produced MX, which is contrary to the results of other researchers. The whole procedure was investigated and it was found that the results obtained at scan mode was more reliable than at SIM mode because of the possible interference. The structural characteristic of the precursors of MX is proposed.
