Phosphatidyl ethanol (PEth) is an abnormal phospholipid formed in the erythrocyte membrane exclusively in the presence of ethanol. It is described as exhibiting a high diagnostic sensitivity and specificity for detecting active chronic excessive drinking behaviors. It may also be useful for characterizing the drinking pattern (i.e. identifying binge drinking episodes) and differentiating light-moderate drinking from abstinence.

 Stable isotope labeled PEth is intended for use as an internal standard for the quantification of PEth by LC or GC-mass spectrometry.

If the number, nature and/or location of stable isotope label atoms (D, 15N, 13C) in this molecule don’t fit with your application, don’t hesitate to contact us to discuss your specific needs.
