Oxytocin-d5 Trifluoroacetate

Oxytocin-d5 is a deuterated variant of the naturally occurring hormone oxytocin, distinguished by the replacement of five hydrogen atoms with deuterium (D), a stable and non-radioactive isotope of hydrogen. The incorporation of deuterium atoms into the oxytocin molecule does not significantly alter its biological activity but provides a distinct advantage in mass spectrometric analysis. Oxytocin-d5 serves as an internal standard in various analytical techniques, especially in liquid chromatography-mass spectrometry (LC-MS), allowing for more precise and accurate quantification of oxytocin in complex biological samples. This is in studies that investigate the role and dynamics of oxytocin in biological systems, where accurate measurement is essential for understanding its physiological and biochemical pathways. The use of oxytocin-d5 in research also aids in elucidating the hormone′s metabolic pathways and degradation kinetics, as its altered mass due to deuterium enables clear differentiation from endogenous oxytocin in mass spectrometry analyses. Thus, oxytocin-d5 is not only valuable for its direct applications in analytical methodologies but also for its role in advancing the understanding of oxytocin′s function and metabolism in biological research.
