Isotope dilution mass spectral studies on capsaicin analogues

摘要

A series of capsaicin analogues have been synthesised as probable tear gas compounds. These compounds were subjected to mass spectral studies under electron ionization (EI) for their total identification. The fragmentation patterns observed in ortho- and para-substituted compounds have been substantiated by performing isotope dilution experiments and daughter-ion scans using tandem mass spectrometry.
