Hydroxy Tolbutamide-d9 is a deuterated analog of the metabolite hydroxy tolbutamide, which is used in mass spectrometry as an internal standard. This compound is specifically designed to provide a consistent reference point for the quantification of hydroxy tolbutamide in various samples. In research, it assists in the accurate measurement of metabolic profiles, particularly in studies focusing on chemical metabolism and disposition. The incorporation of deuterium atoms into Hydroxy Tolbutamide-d9 increases its mass compared to the non-deuterated counterpart, allowing for differentiation and precise quantification in analytical methods such as liquid chromatography-mass spectrometry (LC-MS). By providing a stable isotopic label, Hydroxy Tolbutamide-d9 aids in elucidating metabolic pathways and the kinetics of related compounds.
