Discovory and Applicatios

Normethyl fentanyl-d₃ hydrochloride salt is a deuterium-labeled analog of normethyl fentanyl, used primarily as an internal standard in analytical and forensic applications. The structure of this compound incorporates three deuterium atoms (heavy hydrogen, represented as D or ²H) in place of three corresponding hydrogen atoms within the normethyl fentanyl scaffold. This isotopic labeling allows for precise differentiation between the labeled compound and the non-labeled version using mass spectrometric techniques, without significantly altering its chemical behavior or chromatographic retention.
