Abstract The potent endectocide 23‐( O ‐methyloximino)‐F28249α and related compounds were identified and characterized by mass spectrometry. The fragmentation pathway of 23‐( O ‐methyloximino)‐F28249α was identified by its high‐resolution mass spectrum and the electron impact unit mass spectra of its homologs. This fragmentation pathway is presented and discussed.
