Abstract

In the absence of analytical reference standards, the combination of thermospray and collision-activated dissociation mass spectrometry has been utilized to separate and identify the presence of several esters of testosterone in imported oil injectables. Structural identifications were based on generic daughter ions considered diagnostic of the steroidal ring structure of these anabolic steroids as well as daughter ions representative of the ester alkyl or aryl side chains.
