“…6 This oxidation capability is also strongly correlated with the substituents. [21][22][23] LogP and PSA Partition coefficient (P) and polar surface area (PSA) are generally considered two of the most important parameters in the biological evaluation of a chemical compound. 24,25 The partition coefficient between a water phase and a non-miscible phase is usually shown as logP (n-octanol is used mainly as the lipidic phase).…”

Continuing our work on hydrazyl free radicals, five triphenylhydrazine derivatives, one a new compound, were synthesized to compare the electronic and molecular properties of these compounds, study the influence of substituents on the phenyl rings, and compare their properties with the parent hydrazines and corresponding anions. These hydrazines demonstrate both acid-base and redox properties. The hydrazine proton can be removed by base, yielding the corresponding anion and both the hydrazines and their anions can be oxidized to the corresponding hydrazyl free radicals. ESR spectra confirmed their formation and X-ray crystallography of one compound confirmed their structures.
