Gas chromatography properties and mass spectrometry fragmentation of anabolic androgenic steroids in doping control: Supplementary data

Aim: This study aimed to investigate the gas chromatographic properties and mass spectrometric
fragmentations of anabolic androgenic steroids (AASs) after trimethylsilylated derivatization. Materials
& methods: A total of 113 AASs were analyzed through gas chromatography-mass spectrometry in the
full-scan mode. Results: New fragmentation pathways yielding m/z 129, 143 and 169 ions were analyzed.
Based on the characteristics of the A-ring, seven classes of drugs were identified and analyzed. Conclusion:
The fragmentation pathway of a new classification of 4-en-3-hydroxyl was reported for the first time. The
relationship between the chemical structures of AASs and their retention time, along with their molecular
ion peak abundance, was also reported herein for the first time.
