Electron impact mass spectra of 3,5,7-triaryl-and -trialkyl-4H-1,2-diazepines
摘要:
AbstractElectron impact mass spectra of 3,5,7‐trisubstituted 4H‐1,2‐diazepines indicate that aryl substituents lead to N2expulsion while alkyl substitutents do not. A common fragmentation pattern is observed and discussed for all alkyldiazepines, most of which are newly reported compounds. Assignments are based on electron impact mass spectra of deuteriated substrates and high resolution mass spectra. A previous interpretation of N2expulsion is corrected.

A method of quantifying a target non-peptidic compound having an amino group contained in one or more biological samples, which comprises a step of producing a difference in the mass of the target non-peptidic compound between samples, by using a combination of two or more kinds of stable isotopes of a compound represented by the formula (I):
wherein R
1
, R
2
and R
3
are the same or different and each is hydrogen, halogen or alkyl, or a salt thereof, as a labeling compound; and a kit and the like usable for such method.
