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.

Lipids appear to play a critical role as regulators of stratum corneum desquamation. In this study, we observed discrete lipid phase transitions at physiologic temperatures in both normal human scale (NHS) and in lipid extracts of NHS by differential scanning

Electron paramagnetic resonance (EPR) is a spectroscopic technique that allows detection of paramagnetic compounds, e.g., free radicals, in skin, and is used for measuring skin membrane fluidity and polarity. EPR imaging is concerned with spatially resolved EPR spectroscopy. We studied
