3-CYANO-2,2,5,5-TETRAMETHYL-1-PYRROLIDINYLOXY Usage And Synthesis

Uses

3-Cyano-PROXYL is a stable free radical that can be used in the ESR technique as a nitroxide standard:

• For the estimation of relative concentrations of the spin adducts of 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) with ·OH and O₂^.- radicals.
• For the determination of free radicals present in an aqueous cigarette tar extract.

Definition

ChEBI: 3-cyano-PROXYL is a member of aminoxyls and a pyrrolidinecarbonitrile. It is functionally related to a PROXYL.
