The 5‐bromo, 5‐iodo, and 5‐nitro derivatives of 6‐methyl‐3‐nitroso‐2,4‐pyridinediol were synthesized and shown to produce colored complexes with a number of Group VIII metal ions. Also synthesized were the 1‐pentyl and 1‐octyl esters of 4,6‐dihydroxy‐5‐nitrosopyridine‐3‐carboxylic acid. These compounds showed potential as solvent extraction reagents for certain Group VIII metals.
