rac 8-Hydroxy Efavirenz-d4 (CAS 1246812-30-5)

rac 8-Hydroxy Efavirenz-d4 is a deuterium-labeled metabolite of Efavirenz, a compound utilized in research related to the study of metabolism and kinetics. This particular compound is used as an internal standard for mass spectrometry applications to allow for more accurate quantification of Efavirenz metabolites in biological samples. The incorporation of deuterium atoms at specific positions of the molecule provides a stable isotopic label that does not significantly alter the metabolic profile compared to the non-labeled substance. Researchers use rac 8-Hydroxy Efavirenz-d4 to investigate the enzyme kinetics of the cytochrome P450 system, which is responsible for the metabolism of a wide range of xenobiotics, including Efavirenz. Studies involving rac 8-Hydroxy Efavirenz-d4 help to elucidate the metabolic pathways and identify potential interactions with other substances that may influence the metabolism of Efavirenz. The use of a racemic mixture allows researchers to study the behavior of both enantiomers during metabolic processes.
