Resolution of Unexpected Reference Standard Components of (5R,S)-isoprostane F_(2α) Type VI (iPF_(2α)-VI) Using a Shallow UHPLC-MS/MS Gradient

摘要

No connection was verifed between observed peaks in the reference material and potential late-eluting ethyl ester or lactone components. The consistency of product ion spectra would suggest that the contaminants were other diastereomers. The project is on hold while further characterization or alternate sourcing of reference material is debated internally.
