QUICK LINKS

Desipramine-d3 is a tricyclic antidepressant that functions by inhibiting the reuptake of norepinephrine and serotonin in the central nervous system. It is a deuterated form of desipramine, which means that some of the hydrogen atoms in the compound have been replaced with deuterium, a stable isotope of hydrogen. This labeling with deuterium allows for the use of desipramine-d3 in metabolic studies, as it can be distinguished from the non-labeled compound in biological systems. Desipramine-d3 is used as an internal standard in mass spectrometry-based assays to quantify desipramine levels in biological samples.
