Application
Di-tert-butyl nitroxide (DTBN) can be used as:
- An additive for the synthesis of N-sulfenylimines by oxidative coupling of amines and disulfides or thiols using a copper-based metal-organic framework (MOF) as a catalyst.
- An initiator in the controlled radical polymerization reactions.
- A reagent in the preparation of N-aroyl-o-aroyl-N-tert-butylhdroxylamines by reacting with aromatic acid chlorides.
Reagent for the room-temperature oxidation of primary and secondary benzylamines to imines and for the ESR study of Lewis acid centers in Zeolite X.
Spin label. Has been used in localization of lipid microdomains and thermal phenomena in murine stratum corneum.

Oxidation of human LDL is implicated as an initiator of atherosclerosis. Isolated low density lipoprotein (LDL) and high density lipoprotein (HDL2) were exposed to aqueous radicals generated from the thermolabile azo compound 2,2'-azobis(2-amidinopropane) dihydrochloride. The primary nonpolar lipid products formed
