2,2-Di-(4-tert-octylphenyl)-1-picrylhydrazyl as an Alkane-Soluble Standard for Electron Paramagnetic Resonance Studies

The title compound, a "waxy DPPH" was synthesized in three steps from p,p'-di-tert-octyldiphenylamine.The new radical showed spectral properties that were nearly identical to those of 2,2-diphenyl-1-picrylhydrazyl (DPPH), and it easily dissolved in all or
