Abstract
The discovery of 9-(2-pyridyl)-acenaphtho[ 1,2-e]-as-triazine and its sulfonated form, having particular advantages when used as both a chelator and indicator of ferrous ions in organic or aqueous mediums; a process for the synthesis of those compounds in which hydrazine is used as both a reactant and as a solvent in production of intermediate compounds, eliminating the need of ethanol and the disadvantageous ether-extraction step; the use of N,N-dimethylformamide as a reaction solvent in the production of triazines; the use of the new triazine compounds to measure iron, transferrin, and UIBC/TIBC in biological systems; the use of dimethylsulfoxide and certain processes to eliminate interferences commonly encountered in these assays; and the use of the triazine compounds to measure both total and/or reduced iron in a variety of matrices.
