Notes:
Under ammonia and methane chemical ionization conditions, using a liquid chromatographic moving belt interface for sample introduction, molecular weight information has been observed for two representative N-phenylcarbamates, propham (isopropyl N-phenylcarbamate) and chlorpropham [isopropyl N-(3-chlorophenyl)carbamate]. Displacement reactions can occur in which the side-chain is expelled as a neutral olefin via a hydrogen rearrangement. The temperature dependence of these spectra has been studied and the relative concentration of [MH]+ ions increases with decreasing temperature.
