Detection of 17alpha-hydroxyprogesterone caproate in equine plasma by gas chromatography/tandem mass spectrometry. | LitMetric

Detection of 17alpha-hydroxyprogesterone caproate in equine plasma by gas chromatography/tandem mass spectrometry.

Rapid Commun Mass Spectrom

Australian Racing Forensic Laboratory, P.O. Box 528, Kensington, NSW 1465, Australia.

Published: July 2007

A method was developed for the analysis of the synthetic progestin 17alpha-hydroxyprogesterone caproate in equine plasma following its administration by intramuscular injection. The method employed a reversed-phase solid-phase extraction followed by enol-trimethylsilylation and analysis by gas chromatography/tandem mass spectrometry. The intact ester was detectable in the plasma for up to 2 weeks after a single therapeutic dose, and was found to be stable in equine whole blood for at least 2 months.
