Mass spectrometry of methyltetrazoles

Abstract

Abstract The mass spectra of tetrazole, all isomers of monomethyl‐ and dimethyltetrazole, several trifluoromethyl substituted tetrazoles, as well as deuterated analogs, were recorded. Loss of N 2 was the important fragmentation of the molecular ions of tetrazole and 2‐methyl substituted tetrazoles; however, HN 2 loss was more important for 1‐methyl substituted tetrazoles. The 1‐methyl‐tetrazoles showed molecular ion peaks while the 2‐methyltetrazoles exhibited an unprecedented [M + 1] peak with no molecular ion.
