This deuterated compound, [2-(6-Amino-9H-purin-9-yl)ethanol-d4, is primarily used as a stable isotope-labeled internal standard or reference material in chemical and biological analyses, especially in research on the metabolism of nucleoside or nucleotide compounds. It facilitates the tracking and quantification of related substances in biological samples such as blood, urine, or tissues, enhancing understanding of drug mechanisms and biomolecular functions.

Additionally, it is applied in pharmacological research to study drug distribution and elimination in the body, contributing to the development of new pharmaceuticals or the improvement of existing formulations for greater efficacy.

Its deuterium labeling also supports advanced techniques like NMR spectroscopy for structural elucidation and isotopic tracing in metabolic pathways.
