Narcotics of dialkylaminodithienylbutene series were oxidatively decomposed with 30% hydrogen peroxide and 2-thienyl ketone was obtained as its neutral portion. This ketone was derived to 2, 4-dinitrophenylhydrazone and its determination was carried out by paper chromatography or by visible light spectrum. The dialkylamine obtained from the volatile basic portion was identified by paper chromatography. This method will be possible for determination of narcotics of dialkylaminodithienylbutene and discrimination of dimethylamino, methylethylamino, and diethylamino homologs.
