β¦ Synopsis
The electron impact mass spectra of a series of compounds related to the anthelmintic substance praziquantel are described in sufficient detail to permit their assay in biological samples by selected ion monitoring.

The electron impact induced fragmentation of a large number of 2 and QS-(2-naphthoxy)-polymethylenethiouracils is discussed in detail, with the aid of exact mass measurements and observation of metastable decompositions. The 2 and Qthiopyrimidine structures can be easily distinguished by their mass
The mass spectrometric fragmentation behaviour of pyridazine and four monosubstituted derivatives containing a phenylalkyl side-chnin (3-and dbenzylpyridazine, 3-and 4-Q-phenylethyl)pyridazine) was investigated. In the electron impact ionization mass spectra of the hubstituted compounds abundant [ M
