blue crystals | [Description]
PTIO is an oxidizing reagent that reacts with nitric oxide to form nitric dioxide and corresponding imino nitroxides. It can be used to assay nitric oxide production when examining nitric oxide synthase inhibitory activity. | [Uses]
2-phenyl-4, 4, 5, 5,-tetramethylimidazoline-1-oxyl 3-oxide (PTIO) has been used as a nitric oxide (NO) scavenger. | [Uses]
PTIO is a nitric oxide (NO) radical scavenger used to inhibit physiological effects of NO. | [Synthesis Reference(s)]
