would be a broad O-H peak around 3600-3200 cm-1 but instead there is a peak at 3339.63 cm-1 and 3419.74 cm-1 indicating N-H functional groups; the two peaks indicate a primary amine group. A peak around 3222.39 cm-1 indicates the C-H group from the benzene ring of benzocaine while the peak at 2981.93 cm-1 suggests the C-H methyl group on the structure as well; a peak at 1679.91 cm-1 indicates the C=O from the carbonyl group. The critical observation from the IR analysis is the loss of the carbonyl group

Beta-HCH was present in elevated levels in some patients as recently as 2009. It was manufactured by exhausting chlorination of benzene and for this reason was called erroneously beta-BHC. This synnonym still persists. In March 2005‚ the Italian
