| Abstract: | An aromatic substrate for hydroxylation by OH radicals has been synthesized. Neither the substrate nor its hydroxylated product binds either iron(III) or iron(II). A spectrophotometric assay based on the hydroxylation of this substrate, N,N'-(5-nitro-1,3-phenylene)bisglutaramide, is described. |
