✦ Synopsis

The [M+ U]^+^‐Peak in the Mass Spectra of Diamines

The mass spectra of di‐ and polyamines containing a 1,2‐ethandiamine or a 1,3‐propandiamine unit are quite often characterized by [M+ 1l]^+^‐peaks. It is demonstrated that these peaks correspond to a fragment‐ion formed by loss of H. from a formaldehyde‐condensation product (e. g. 15) or by loss of CH^3^. from a acetaldehyde‐condensation product (e. g. 16) with the diamine. The aldehydes are usually impurities in solvents (especially methanol) used by chromatography, synthesis etc. of the diamines.
