Dodecyltrimethylammonium-d34(bromide)

Dodecyltrimethylammonium-d34 (bromide) is the deuterium labeled Dodecyltrimethylammonium (bromide)[1]. Dodecyltrimethylammonium bromide (DTAB) is a surfactant. Dodecyltrimethylammonium bromide interacts with DNA and changes the mechanical properties of DNA on binding and the specific binding parameters of the interaction[2].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
